About Imperial gallon (imp gal)

The imperial gallon is a unit of volume defined as exactly 4.54609 liters, used in the United Kingdom, Canada, and some Commonwealth nations. It is approximately 20% larger than the US liquid gallon. Fuel economy in the UK is expressed in miles per imperial gallon. The imperial gallon divides into 8 imperial pints, each of 568 mL. The UK officially metricated fuel sales to liters in the 1980s–1990s, but miles per imperial gallon remains the legal unit for new car fuel economy labels.

UK car fuel economy figures are expressed in miles per imperial gallon. One imperial gallon equals 8 standard UK pints of beer.

About Deciliter (dl)

A deciliter (dL) is one tenth of a liter (0.1 L), equal to 100 milliliters. It is used in clinical laboratory medicine for reporting blood test results (blood glucose, haemoglobin, cholesterol in mg/dL or g/dL), in European nutrition labeling, and in Scandinavian cooking recipes. Despite its limited everyday use as a liquid measure, the deciliter is one of the most medically significant volume units — nearly every blood test result references it.

Blood glucose is reported in mg/dL. A small yoghurt pot or juice glass holds roughly 1–2 dL.


Imperial gallon – Frequently Asked Questions

One imperial gallon is defined as exactly 4.54609 liters — approximately 20% more than the US liquid gallon (3.785 L).

The UK switched fuel sales to liters in the 1990s. However, miles per gallon (imperial) remains the legal unit for car fuel economy on new vehicle labels. Road speed is in mph and distances are in miles, so imperial gallons remain embedded in UK motoring.

UK MPG uses the imperial gallon (4.546 L); US MPG uses the US gallon (3.785 L). Multiply UK MPG by 0.832 to get US MPG. A car rated 40 UK MPG ≈ 33 US MPG.

There are exactly 8 imperial pints in one imperial gallon. Each imperial pint is 568 mL, compared to 473 mL for a US pint.

Canada officially metricated in the 1970s and fuel is sold in liters. However, some older Canadians and certain agricultural contexts still reference imperial gallons informally. Canadian and UK imperial gallons are identical (4.54609 L).

Deciliter – Frequently Asked Questions

Deciliters are the standard reference volume for blood test results. Blood glucose is reported in mg/dL, haemoglobin in g/dL, and cholesterol in mg/dL. Normal fasting blood glucose is 70–99 mg/dL.

One deciliter (dL) equals 100 milliliters (mL). Since 1 dL = 0.1 L and 1 mL = 0.001 L, there are exactly 100 mL per dL.

Yes, in Scandinavia (Sweden, Norway, Denmark) recipes commonly list liquid ingredients in deciliters. 1 dL is roughly 6–7 tablespoons or just under half a US cup.

A normal fasting blood glucose is 70–99 mg/dL. Pre-diabetes is 100–125 mg/dL. Diabetes is diagnosed at ≥126 mg/dL on two separate tests. Post-meal levels should be below 140 mg/dL in non-diabetics.

One deciliter (100 mL) is roughly 0.42 US cups. Conversely, one US cup is about 2.4 dL. For Scandinavian recipes, 1 dL ≈ just under half a cup.
