Butter (Melted) weighs 0.911 kg per litre. Convert litres to kilograms (and back) using its exact density.
Quick Metrology Summary
1 liter of Butter (Melted) weighs approximately 0.911 kilograms (or 911 grams) at standard room temperature. Because mass equals volume multiplied by density (\(m = V \times \rho\)), multiplying volume in liters by 0.911 gives the exact mass in kg.
Butter (Melted): Weight per Litre Explained
Butter (Melted) has a density of 0.911 kg/L, which makes it 8.9% lighter than water. Melted butter is about 80% milk fat with water and milk solids, giving 0.911 kg/L. Solid butter is slightly denser in a block but contains air pockets when whipped, so melted volume is the reliable basis for this conversion.
When You Need This Conversion

What Changes the Density
Salted and unsalted butter differ by a hair. Cold, solid butter measured by volume can weigh anywhere from 0.9 to 0.96 kg/L depending on how tightly it is packed.

How to Convert Liters of Butter (Melted) to Kilograms
Melted butter is about 80% milk fat with water and milk solids, giving 0.911 kg/L. Solid butter is slightly denser in a block but contains air pockets when whipped, so melted volume is the reliable basis for this conversion. To convert, multiply the volume in litres by 0.911. To go the other way, divide the weight in kilograms by 0.911.
kg = Litres × 0.911
L = kg ÷ 0.911
1 L → 0.911 kg
10 L → 9.11 kg
100 L → 91.1 kgExample
Convert 5 litres of butter (melted) to kilograms: 5 × 0.911 = 4.555 kg, or 10.04 lb. Reversed: 4.555 kg ÷ 0.911 = 5 L.
Worked examples
| Scenario | Calculation | Result |
|---|---|---|
| 1 L of butter (melted) | 1 × 0.911 kg/L | 0.911 kg |
| 5 L of butter (melted) | 5 × 0.911 kg/L | 4.555 kg |
| 20 L of butter (melted) | 20 × 0.911 kg/L | 18.22 kg |
| 100 L of butter (melted) | 100 × 0.911 kg/L | 91.1 kg |
| 10 kg of butter (melted) (reverse) | 10 ÷ 0.911 kg/L | 10.98 L |
