How Compost kg to Liters Converter Works?

The Compost kg to Liters Converter works in 3 steps.

  1. 1

    Enter the mass of compost in kilograms (kg).

  2. 2

    Keep 0.65 kg/L for moist, finished compost; dry compost sits near 0.45 kg/L and wet, heavy compost near 0.8 kg/L.

  3. 3

    Read the liters (L), the unit printed on most compost bags.

Compost kg to Liters Converter Formula

The Compost kg to Liters Converter formula is:

Volume (L) = Mass of compost (kg) ÷ 0.65 kg/L

The reverse formula is Mass (kg) = Volume of compost (L) × 0.65 kg/L.

Worked example

10 kg (22.05 lb) of compost ÷ 0.65 kg/L = 15.38 L (4.064 US gal).

Garden compost bags list liters, not kilograms. 2 bags of 40 L give 80 L, enough to spread 25 mm (1 in) of mulch over about 3.2 m².
