Quick Metrology Summary

1 liter of Hydraulic Oil weighs approximately 0.875 kilograms (or 875 grams) at standard room temperature. Because mass equals volume multiplied by density (\(m = V \times \rho\)), multiplying volume in liters by 0.875 gives the exact mass in kg.

Hydraulic Oil: Weight per Litre Explained

Hydraulic Oil has a density of 0.875 kg/L, which makes it 13% lighter than water. ISO VG 46 hydraulic oil is a refined mineral oil with additives and weighs about 0.875 kg/L, which is within a few percent of engine oil.

When You Need This Conversion

Excavator and press reservoir fills, system flushing, cylinder and accumulator volume checks and waste-oil handling.

What Changes the Density

Water-glycol and synthetic fire-resistant fluids are noticeably heavier, around 1.05–1.1 kg/L. Check the datasheet rather than assuming mineral oil.

How it works

  1. Enter the litres of hydraulic oil

    Type the volume in litres. The calculator is preset to Hydraulic Oil at 0.875 kg/L.

  2. Switch direction if needed

    Flip to kilograms → litres to find how much space a given weight of hydraulic oil takes up.

  3. Read the result

    See kilograms, pounds, millilitres and gallons. Each litre adds 0.875 kg.

How to Convert Liters of Hydraulic Oil to Kilograms

ISO VG 46 hydraulic oil is a refined mineral oil with additives and weighs about 0.875 kg/L, which is within a few percent of engine oil. To convert, multiply the volume in litres by 0.875. To go the other way, divide the weight in kilograms by 0.875.

Convert Liters to KG formula and density calculation diagram
kg = Litres × 0.875
L  = kg ÷ 0.875

1 L   → 0.875 kg
10 L  → 8.75 kg
100 L → 87.5 kg
Example

Convert 5 litres of hydraulic oil to kilograms: 5 × 0.875 = 4.375 kg, or 9.65 lb. Reversed: 4.375 kg ÷ 0.875 = 5 L.
