How do you convert imperial gallons to imperial gills? The converter and the working

  1. 1.Take the measurement in imperial gallons.
  2. 2.Multiply by 32 — that is how many imperial gills fit in one imperial gallon.
  3. 3.To go back the other way, divide by 32, or multiply by 0.03125.

Worked example: 25 imperial gallons to imperial gills

Formula
gal (UK) × 32 = gi (UK)
Arithmetic
25 × 32 = 800 gi (UK)
Answer
25 gal (UK) = 800 gi (UK)

The factor is exact, so this figure is exact too — only the display is rounded.

What is an imperial gallon?

Exactly 4.54609 liters since 1985, and the reason UK and US fuel economy figures cannot be compared: it is 20% larger than the US gallon, so 40 mpg in Britain is about 33 mpg in America on the same car.

What is an imperial gill?

A quarter of an imperial pint, 142.0653125 ml exactly. It survives as the measure spirits were once poured by in British pubs, and in old recipes that ask for a gill of cream.

How many imperial gills are in an imperial gallon?

One imperial gallon is 32 imperial gills, exactly. Going the other way, one imperial gill is 0.03125 imperial gallons. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
