About Converting Pounds per Imperial gallon to Grams per Liter
Pound per Imperial gallon and Gram per Liter 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 liter = pounds per imperial gallon × 99.7763726631
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per imperial gallon equals 99.7763726631 base units, and 1 gram per liter equals 1 base unit, so dividing one by the other gives the direct pound per imperial gallon-to-gram per liter factor of 99.7763726631.
Simple example
1 lb/imp gal × 99.77637266 = 99.77637266 g/L
1 pound per imperial gallon = 99.77637266 grams per liter.
Real-world example
1,000 lb/imp gal × 99.77637266 = 99,776.37266 g/L
1,000 pounds per imperial gallon = 99,776.37266 grams per liter.

What is a pound per imperial gallon?
Pound per Imperial gallon (lb/imp gal) is a unit of density.
What is a gram per liter?
Gram per Liter (g/L) measures mass concentration. One gram of a substance dissolved or dispersed per liter of total solution or mixture volume. It is classified as a metric derived concentration unit.
Is the pound per imperial gallon to gram per liter conversion exact?
