Isopropyl Alcohol (99%) weighs 0.786 kg per litre. Convert litres to kilograms (and back) using its exact density.
Quick Metrology Summary
1 liter of Isopropyl Alcohol (99%) weighs approximately 0.786 kilograms (or 786 grams) at standard room temperature. Because mass equals volume multiplied by density (\(m = V \times \rho\)), multiplying volume in liters by 0.786 gives the exact mass in kg.
Isopropyl Alcohol (99%): Weight per Litre Explained
Isopropyl Alcohol (99%) has a density of 0.786 kg/L, which makes it 21% lighter than water. 99% isopropyl alcohol (IPA) weighs 0.786 kg/L, almost identical to acetone and to ethanol.

How to Convert Liters of Isopropyl Alcohol (99%) to Kilograms
99% isopropyl alcohol (IPA) weighs 0.786 kg/L, almost identical to acetone and to ethanol. To convert, multiply the volume in litres by 0.786. To go the other way, divide the weight in kilograms by 0.786.
kg = Litres × 0.786
L = kg ÷ 0.786
1 L → 0.786 kg
10 L → 7.86 kg
100 L → 78.6 kgExample
Convert 5 litres of isopropyl alcohol (99%) to kilograms: 5 × 0.786 = 3.93 kg, or 8.66 lb. Reversed: 3.93 kg ÷ 0.786 = 5 L.
Worked examples
| Scenario | Calculation | Result |
|---|---|---|
| 1 L of isopropyl alcohol (99%) | 1 × 0.786 kg/L | 0.786 kg |
| 5 L of isopropyl alcohol (99%) | 5 × 0.786 kg/L | 3.93 kg |
| 20 L of isopropyl alcohol (99%) | 20 × 0.786 kg/L | 15.72 kg |
| 100 L of isopropyl alcohol (99%) | 100 × 0.786 kg/L | 78.6 kg |
| 10 kg of isopropyl alcohol (99%) (reverse) | 10 ÷ 0.786 kg/L | 12.72 L |
