About Converting Milligrams per Gallon to Decigrams per Imperial gallon
Milligram per Gallon and Decigram 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
decigrams per imperial gallon = milligrams per gallon × 0.012009499255
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per gallon equals 0.000264172052358 base units, and 1 decigram per imperial gallon equals 0.0219969248299 base units, so dividing one by the other gives the direct milligram per gallon-to-decigram per imperial gallon factor of 0.012009499255.
Simple example
1 mg/gal × 0.01200949926 = 0.0120094993 dg/imp gal
1 milligram per gallon = 0.0120094993 decigrams per imperial gallon.
Real-world example
1,000 mg/gal × 0.01200949926 = 12.00949926 dg/imp gal
1,000 milligrams per gallon = 12.00949926 decigrams per imperial gallon.

Frequently asked questions
How many decigrams per imperial gallon are in 1 milligram per gallon?
1 milligram per gallon equals 0.0120094993 decigrams per imperial gallon, using the exact defined conversion factor rather than an estimate.
How do I convert milligram per gallon to decigram per imperial gallon?
Multiply the milligram per gallon value by 0.01200949926. The converter above does this instantly to whatever precision you set.
How do I convert decigram per imperial gallon back to milligram per gallon?
Use the reverse factor: 1 decigram per imperial gallon equals 83.26741846 milligrams per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a milligram per gallon?
Milligram per Gallon (mg/gal) is a unit of density.
What is a decigram per imperial gallon?
Decigram per Imperial gallon (dg/imp gal) is a unit of density.
Is the milligram per gallon to decigram per imperial gallon conversion exact?
Yes. Both milligram per gallon and decigram per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.01200949926 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.
