About Converting Micrograms per Gallon to Micrograms per Imperial gallon
Microgram per Gallon and Microgram per Imperial 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
micrograms per imperial gallon = micrograms per gallon × 1.2009499255
This factor comes from each unit's defined relationship to the category's base unit: 1 microgram per gallon equals 2.641721e-7 base units, and 1 microgram per imperial gallon equals 2.199692e-7 base units, so dividing one by the other gives the direct microgram per gallon-to-microgram per imperial gallon factor of 1.2009499255.
Simple example
1 ug/gal × 1.200949926 = 1.200949926 ug/imp gal
1 microgram per gallon = 1.200949926 micrograms per imperial gallon.
Real-world example
1,000 ug/gal × 1.200949926 = 1,200.949926 ug/imp gal
1,000 micrograms per gallon = 1,200.949926 micrograms per imperial gallon.

How do I convert microgram per imperial gallon back to microgram per gallon?
Use the reverse factor: 1 microgram per imperial gallon equals 0.8326741846 micrograms per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a microgram per gallon?
Microgram per Gallon (ug/gal) is a unit of density.
What is a microgram per imperial gallon?
Microgram per Imperial gallon (ug/imp gal) is a unit of density.
Is the microgram per gallon to microgram per imperial gallon conversion exact?
Yes. Both microgram per gallon and microgram per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 1.200949926 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.
