A litre of ghee weighs about 915 grams, not a full kilogram, and a kilogram of ghee fills about 1.09 litres. Both figures come from the density of milk fat at 20 °C, 915 kg per cubic metre or 0.915 g per ml: 1,000 ml × 0.915 = 915 g, and 1,000 g ÷ 0.915 = 1,093 ml. The exact weight shifts a little with temperature and with which published figure you use.
At a glance
- A litre of ghee weighs about 915 g: milk fat has a density of 0.915 g per ml at 20 °C in the University of Guelph's dairy science text.
- Multiply millilitres by 0.915 for grams and divide grams by 0.915 for millilitres: 500 ml is about 458 g, 850 ml about 778 g, and 1 kg about 1.09 litres.
- Older Indian figures quoted in a National Dairy Research Institute thesis put cow ghee's specific gravity at 0.9358 to 0.9443 at 30 °C, so the exact weight depends on temperature and source.
- Set, grainy ghee traps air, so weigh it rather than measuring it by cup.
- India's packaged-commodity rules allow a weight or volume declaration for edible oil, vanaspati ghee and butter oil, and legal summaries of a 2023 amendment say a volume-labelled pack must also show its weight.
How much does 1 litre of ghee weigh in kg?
About 0.915 kg. Ghee is almost entirely milk fat, and the University of Guelph's dairy science text gives the density of milk fat at 20 °C as 915 kg per cubic metre. A litre is one thousandth of a cubic metre, so a litre of ghee at that temperature weighs about 915 g, or 0.915 kg.
Using a milk fat figure for ghee is reasonable because of how ghee is defined. Under FSSAI's standard for milk fat products, ghee is made by processes that remove almost all the water and milk solids-not-fat, and it must contain at least 99.5 per cent milk fat with no more than 0.5 per cent moisture. What is in the jar is, for practical purposes, milk fat.
How many litres is 1 kg of ghee?
About 1.09 litres. Divide the mass by the density: 1,000 g ÷ 0.915 g/ml = 1,092.9 ml. So a 1 kg pack holds roughly 9 per cent more ghee than a 1 litre jar (1,092.9 ÷ 1,000 = 1.093), and a 500 g pack holds about 546 ml. The two pack types are not interchangeable on a shelf.
One litre equals one kilogram only for something with a density of 1 kg per litre. Milk fat sits at about 0.915 kg per litre, so every litre of ghee falls about 85 g short of a kilogram (1,000 − 915 = 85 g).
What is the density of ghee in g/ml?
About 0.915 g per ml at 20 °C, the milk fat figure from the Guelph text. A 2010 master's thesis from the National Dairy Research Institute (NDRI), Karnal, cites the dairy chemists Walstra and Jenness for the same value. No opened source gives a density measured on ghee itself at 20 °C, so 0.915 is the figure behind every conversion here.
Dairy chemistry texts often report specific gravity instead. The NDRI thesis explains that the density of liquid fats is commonly expressed as specific gravity rather than absolute density, that it depends on composition and on the temperature of measurement, and it quotes Rangappa and Achaya (1974) for cow ghee at 30 °C: 0.9358 to 0.9443, with buffalo ghee at 0.9340 to 0.9444. Those values are higher than 0.915, and the thesis does not give the reference conditions, so we use them only as a cross-check. Taken at face value, they would put a litre at about 936 to 944 g (1,000 × 0.9358 and 1,000 × 0.9443).
The same thesis quotes a density range of 0.910 to 0.927 at 20 °C for most edible vegetable oils and fats, and reports that a 1973 study of ghee and animal body fats at 40 °C concluded that, with differences that narrow, adulteration may not be detectable from density. Ghee weighs about what cooking oils weigh, so density alone will not tell you whether a jar is pure; that takes the tests in our guide to reading a ghee lab report.
Does temperature or set ghee change the weight?
The weight of the ghee in a jar does not change, but the space it takes up does, so a litre of it can weigh slightly more or less. The Guelph text's chapter on the physical properties of milk says density depends on the temperature at measurement, the material's temperature history, its composition and any trapped air. A per-litre weight is only exact for one stated temperature.
The same chapter's table shows the effect for cream: heavy cream at 36.6 per cent fat is 1.008 kg per litre at 4.4 °C, 0.994 at 20 °C and 0.978 at 38.9 °C. Across its rows at 20 °C, skim milk is 1.033, whole milk at 4 per cent fat 1.030 and heavy cream 0.994: the more fat, the lower the density, with ghee at the far end of that line. No opened source gives ghee's density at a series of temperatures, so we do not put a number on how much a warm litre differs from a cool one.
Set ghee raises a practical problem. Guelph lists trapped air as a complication when measuring thicker products, and grainy, set ghee spooned into a cup can leave air gaps, so a cup of set ghee is rougher than a cup of melted ghee. If you need an accurate quantity, weigh it. Our piece on why ghee turns grainy, or danedar, covers the texture itself.
How do you convert ghee from litres to kg and back?
Multiply millilitres by 0.915 to get grams, and divide grams by 0.915 to get millilitres. Both steps use the Guelph density for milk fat at 20 °C, so every figure below is a typical value, not a measurement of your jar.
- Write the quantity in millilitres or grams: 1 litre = 1,000 ml, 1 kg = 1,000 g.
- Volume to weight: grams = millilitres × 0.915.
- Weight to volume: millilitres = grams ÷ 0.915.
- Round to the nearest gram; the figure is typical, not exact.
| Pack size | Arithmetic (0.915 g per ml, milk fat at 20 °C) | Result |
|---|---|---|
| 250 ml | 250 × 0.915 = 228.75 g | about 229 g |
| 500 ml | 500 × 0.915 = 457.5 g | about 458 g |
| 850 ml | 850 × 0.915 = 777.75 g | about 778 g |
| 900 ml | 900 × 0.915 = 823.5 g | about 824 g |
| 1 litre (1,000 ml) | 1,000 × 0.915 = 915 g | about 0.915 kg |
| 2 litres (2,000 ml) | 2,000 × 0.915 = 1,830 g | about 1.83 kg |
| 250 g | 250 ÷ 0.915 = 273.2 ml | about 273 ml |
| 500 g | 500 ÷ 0.915 = 546.4 ml | about 546 ml |
| 1 kg (1,000 g) | 1,000 ÷ 0.915 = 1,092.9 ml | about 1.09 litres |
| 2 kg (2,000 g) | 2,000 ÷ 0.915 = 2,185.8 ml | about 2.19 litres |
The same factor works for price. A litre holds about 0.915 kg, so the price of a litre divided by 0.915 gives its price per kilo. That is the fair way to set a litre jar against a kilo pack. Our article on what drives A2 ghee prices in India covers why the prices themselves differ so widely.
Is ghee sold in litres or kg in India?
Both, because the packaging rules allow either. The Legal Metrology (Packaged Commodities) Rules, 2011 require solid, semi-solid or viscous goods to be declared by mass and liquids by volume, except for the commodities in their Fourth Schedule. Item 11 of that schedule reads "Edible oil, Vanaspati ghee and butter oil", declared by "weight or volume". The line has no comma after "Vanaspati", so it can be read as vanaspati ghee rather than ghee itself; butter oil, which FSSAI covers in the same standard as ghee, is named either way.
The 2011 text we read also fixed pack sizes. Its Second Schedule listed "Edible Oils Vanaspati, ghee, butter oil", with ghee named on its own, in standard sizes from 50 g to 5 kg or the same numbers in millilitres or litres, and asked volume-labelled packs to show the equivalent mass in brackets.
The rules have changed since. We could not open the gazette notifications, so what follows rests on law-firm summaries. One says an amendment of 28 March 2022 omitted the Second Schedule, so the fixed pack-size list no longer applies, after its start date was pushed back more than once. Another says a 6 October 2023 amendment rewrote the Fourth Schedule entry as "weight or volume and if the net quantity is declared by volume, the net quantity shall also be declared by weight", effective 1 January 2024. Check the current consolidated rules before relying on this for a business decision.
What should you check on a ghee label?
Check whether the net quantity is stated in ml or litres, or in g or kg, and convert before comparing two packs. A 1 litre jar and a 1 kg pack are not the same amount of ghee. If the pack shows both a volume and a weight, you can read the packer's own density off the label.
- Unit: volume (ml, L) or mass (g, kg). Convert one into the other with the 0.915 factor before you compare.
- Paired weight: if a volume pack also shows a mass, divide the mass by the volume to see what density the packer has assumed, and compare it with 0.915.
- Price per unit: work out a price per kilo for every pack you are comparing, using the arithmetic above.
- Batch details: net quantity tells you how much ghee is in the jar, not how good it is. For that, look for a batch code and a published laboratory report.
Every Himdhara jar carries a batch code, and the laboratory report for each batch is published on our lab reports page before that batch ships. If you are choosing our A2 bilona ghee, convert its pack size with the same arithmetic as any other.
The short version
A litre of ghee weighs about 915 g and a kilogram fills about 1.09 litres, based on a milk fat density of 0.915 g per ml at 20 °C. To convert, multiply millilitres by 0.915 for grams, or divide grams by 0.915 for millilitres, so 500 ml is about 458 g and 850 ml about 778 g. The figure moves a little with temperature and between published sources, and set ghee is best weighed rather than measured by cup. India's packaging rules allow ghee to be declared by weight or volume, and legal summaries of a 2023 amendment say a volume-labelled pack must also show its weight, so convert before you compare packs or prices.
