About Converting Grams per Gallon to Grams per Cubic Meter
Gram per Gallon and Gram per Cubic Meter 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
grams per cubic meter = grams per gallon × 264.172052358
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per gallon equals 0.264172052358 base units, and 1 gram per cubic meter equals 0.001 base units, so dividing one by the other gives the direct gram per gallon-to-gram per cubic meter factor of 264.172052358.
Simple example
1 g/gal × 264.1720524 = 264.1720524 g/m3
1 gram per gallon = 264.1720524 grams per cubic meter.
Real-world example
1,000 g/gal × 264.1720524 = 264,172.0524 g/m3
1,000 grams per gallon = 264,172.0524 grams per cubic meter.

Frequently asked questions
How many grams per cubic meter are in 1 gram per gallon?
1 gram per gallon equals 264.1720524 grams per cubic meter, using the exact defined conversion factor rather than an estimate.
How do I convert gram per gallon to gram per cubic meter?
Multiply the gram per gallon value by 264.1720524. The converter above does this instantly to whatever precision you set.
How do I convert gram per cubic meter back to gram per gallon?
Use the reverse factor: 1 gram per cubic meter equals 0.0037854118 grams per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per gallon?
Gram per Gallon (g/gal) is a unit of density.
What is a gram per cubic meter?
Gram per Cubic Meter (g/m3) is a unit of density.
Is the gram per gallon to gram per cubic meter conversion exact?
Yes. Both gram per gallon and gram per cubic meter are defined by fixed standards rather than physical artifacts, so the factor of 264.1720524 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.
