About Gallon (UK) (gal (UK))

Definition

The UK (imperial) gallon is a unit of volume equal to 160 UK fluid ounces, or exactly 4.54609 liters.

Mathematical Relationship

1 UK gal = 4 UK qt = 8 UK pt = 160 UK fl oz = 4.54609 L ≈ 1.201 US gal.

Conversion Formula

To liters: multiply by 4.54609. To US gallons: multiply by 1.20095. To cubic meters: multiply by 0.00454609.

Practical Applications

UK road signs (mpg), older fuel consumption references, and some Caribbean and Middle Eastern markets that still use imperial units.

Interesting Facts

A UK gallon is about 20% larger than a US gallon. A car rated at 40 mpg (UK) gets only about 33 mpg (US).

Common Mistakes

Misinterpreting UK mpg as US mpg — UK figures look higher because the imperial gallon is larger.

Educational Tips

UK gallon ≈ 4.55 L ≈ 1.2 US gallons. The UK gallon was defined so that 1 gallon of water = 10 pounds.

About Deciliter (dL)

Definition

The deciliter is a unit of volume equal to one tenth of a liter (10⁻¹ L), or 100 milliliters.

Mathematical Relationship

1 dL = 0.1 L = 100 mL = 100 cm³. There are 10 dL in one liter.

Conversion Formula

To mL: multiply by 100. To liters: divide by 10. To cups (US): multiply by 0.423.

Practical Applications

Scandinavian cooking recipes, clinical blood test concentrations (mg/dL), and European nutritional labels (per 100 mL = 1 dL).

Interesting Facts

In Sweden and Norway, recipes use deciliters instead of cups. Normal blood glucose is 70–100 mg/dL (fasting).

Common Mistakes

Confusing dL with mL in medical contexts — 1 dL = 100 mL, so a result of 100 mg/dL ≠ 100 mg/mL.

Educational Tips

Remember: 'deci' = tenth. 1 dL = a tenth of a liter = 100 mL. Nordic recipes use dL where Americans use cups.
