How Water kg to Liters Converter Works?
The Water kg to Liters Converter works in 3 steps.
- 1
Enter the mass of water in kilograms (kg).
- 2
Keep the density at 1.000 kg/L for cold water, or set 0.998 kg/L for room temperature and 0.958 kg/L for boiling water.
- 3
Read the volume in liters (L), with US gallons and Imperial gallons in the table below.
Water kg to Liters Converter Formula
The Water kg to Liters Converter formula is:
Volume (L) = Mass of water (kg) ÷ 1 kg/LThe reverse formula is Mass (kg) = Volume of water (L) × 1 kg/L.
Worked example
25 kg (55.12 lb) of water ÷ 1 kg/L = 25 L (6.604 US gal).
The metric system defined the original kilogram in 1795 as the mass of 1 liter of water at the melting point of ice. The modern kilogram is defined by the Planck constant, yet 1 L of pure water still weighs 0.99997 kg at 4 °C.
Water kg to Liters Converter Conversion Table
The Water kg to Liters Converter table converts 12 masses of water from 0.5 kg (1.1 lb) to 1,000 kg (2,204.6 lb) into liters (L), US gallons and Imperial gallons at 1 kg/L (8.345 lb per US gallon).
| Mass (kg) | Mass (lb) | Volume (L) | Volume (US gal) | Volume (Imp gal) |

| 1,000 | 2,205 | 1,000 | 264.2 | 220 |
What is Water kg to Liters Converter?
The Water kg to Liters Converter is a calculator that converts a mass of water in kilograms (kg) into volume in liters (L) with temperature-specific water density. Pure water has a density of 0.99997 kg/L at 4 °C (39.2 °F), 0.99821 kg/L at 20 °C (68 °F) and 0.95835 kg/L at 100 °C (212 °F).
Tap water carries dissolved minerals of roughly 0.1 to 0.5 g per liter, so tap water density sits within 0.05% of pure water. The 1 kg = 1 L rule holds for everyday cooking, gardening and filling tanks.
