Quick Metrology Summary

1 liter of Brake Fluid (DOT 4) weighs approximately 1.04 kilograms (or 1040 grams) at standard room temperature. Because mass equals volume multiplied by density (\(m = V \times \rho\)), multiplying volume in liters by 1.04 gives the exact mass in kg.

Brake Fluid (DOT 4): Weight per Litre Explained

Brake Fluid (DOT 4) has a density of 1.04 kg/L, which makes it 4% heavier than water. DOT 4 brake fluid is glycol-ether based. These compounds are denser than water, so it comes in at 1.04 kg/L and sinks in water.

When You Need This Conversion

Bleeding and flushing brake systems, workshop stock and shipping hazardous-goods quantities in kilograms.

What Changes the Density

DOT 3, 4 and 5.1 are all around 1.03–1.07 kg/L. DOT 5 is silicone-based and much lighter, near 0.96 kg/L, and must never be mixed with the others.

How it works

  1. Enter the litres of brake fluid (dot 4)

    Type the volume in litres. The calculator is preset to Brake Fluid (DOT 4) at 1.04 kg/L.

  2. Switch direction if needed

    Flip to kilograms → litres to find how much space a given weight of brake fluid (dot 4) takes up.

  3. Read the result

    See kilograms, pounds, millilitres and gallons. Each litre adds 1.04 kg.

How to Convert Liters of Brake Fluid (DOT 4) to Kilograms

DOT 4 brake fluid is glycol-ether based. These compounds are denser than water, so it comes in at 1.04 kg/L and sinks in water. To convert, multiply the volume in litres by 1.04. To go the other way, divide the weight in kilograms by 1.04.

Convert Liters to KG formula and density calculation diagram
kg = Litres × 1.04
L  = kg ÷ 1.04

1 L   → 1.04 kg
10 L  → 10.4 kg
100 L → 104 kg
Example

Convert 5 litres of brake fluid (dot 4) to kilograms: 5 × 1.04 = 5.2 kg, or 11.46 lb. Reversed: 5.2 kg ÷ 1.04 = 5 L.
