About Converting Pounds per Milliliter to Kilograms per Gallon
Pound per Milliliter and Kilogram per Gallon both measure density — mass per unit volume — a property used to identify materials, check manufacturing quality, and predict whether something floats or sinks. As a fixed reference point, water has a density of exactly 1000 kg/m³ (1 g/cm³, 1 g/mL) at its temperature of maximum density, which is why many density figures in science and engineering are quoted relative to water. Both are mass per volume density units.
Formula
kilograms per gallon = pounds per milliliter × 1717.03390253
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per milliliter equals 453592.37 base units, and 1 kilogram per gallon equals 264.172052358 base units, so dividing one by the other gives the direct pound per milliliter-to-kilogram per gallon factor of 1717.03390253.
Simple example
1 lb/mL × 1717.033903 = 1,717.033903 kg/gal
1 pound per milliliter = 1,717.033903 kilograms per gallon.
Real-world example
1,000 lb/mL × 1717.033903 = 1,717,033.903 kg/gal
1,000 pounds per milliliter = 1,717,033.903 kilograms per gallon.

Mass per volume density.
Understanding the Kilogram per Gallon
Kilogram per Gallon (kg/gal) measures density. A mathematically valid way to express liquid density in kilograms per US gallon. It is classified as a mixed metric/US customary density unit.
Uses of the Kilogram per Gallon today
- Can be used to express liquid density such as fuel or industrial liquids in kilograms per gallon — in practice, kilograms per liter (metric) and pounds per gallon (US customary) are the specific pairings more commonly seen in fuel and liquid-density references
Kilogram per Gallon — sources
- Fuel and petroleum liquid-density references — Liquid density figures for fuels are typically reported in kg/L, kg/m³, or lb/gal rather than kg/gal.

Frequently asked questions
How many kilograms per gallon are in 1 pound per milliliter?
1 pound per milliliter equals 1,717.033903 kilograms per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert pound per milliliter to kilogram per gallon?
Multiply the pound per milliliter value by 1717.033903. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per gallon back to pound per milliliter?
Use the reverse factor: 1 kilogram per gallon equals 0.0005823997 pounds per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a pound per milliliter?
Pound per Milliliter (lb/mL) is a unit of density.
What is a kilogram per gallon?
Kilogram per Gallon (kg/gal) measures density. A mathematically valid way to express liquid density in kilograms per US gallon. It is classified as a mixed metric/US customary density unit.
Is the pound per milliliter to kilogram per gallon conversion exact?
Yes. Both pound per milliliter and kilogram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 1717.033903 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
