Kg to Gallons of Water
Convert kilograms of Water to US liquid gallons, Imperial gallons, and liters using verified reference density (1.0000 kg/L).
10 kg of water (standard) equals approximately 2.64172 US Liquid Gallons.
How Many Gallons Is 1 Kg of Water?
1 kilogram (kg) of pure water equals approximately 0.26417 US liquid gallons (or 0.2200 Imperial gallons) at 20°C (68°F). Conversely, 1 US gallon of water weighs exactly 3.7854 kg (8.345 lbs). Because water density is exactly 1.0000 kg/L, gallons equal mass divided by 3.78541.
Material Metrology & Physical Properties: Water
Pure liquid water serves as the universal physical metrology baseline. Under the International System of Units (SI) and NIST standards, 1 liter of pure water at its maximum density temperature of 3.98°C has a mass of exactly 1.0000 kilogram. Because water expands anomalous below 4°C and above 4°C, temperature control is essential for custody-transfer metrology.
At standard room temperature (20°C / 68°F), water's physical density slightly declines to 0.9982 kg/L due to thermal kinetic expansion. Consequently, 1 US liquid customary gallon of room-temperature water weighs approximately 8.34 pounds (3.7854 kg), while 1 British Imperial gallon equals exactly 10.00 pounds (4.5359 kg) under historical statutory definitions.
In municipal engineering, water treatment, hydrology, and industrial boiler feed management, engineers routinely convert metric kilogram mass flow meter measurements into US customary gallons or acre-feet.
Non-hazardous neutral reference fluid. Account for dissolved solids (TDS) and thermal operating ranges during bulk metering.
