Convert Cubic Yard to UK Gallon (yd³ → gal (UK))

Converting cubic yards to UK gallons is straightforward: multiply by the conversion factor. Follow these three steps to do it by hand or in your head.

1. 1
   Take your value in cubic yards

   Start with the number of cubic yards (yd³) you want to convert.
2. 2
   Multiply by 168.17856

   The conversion factor from yd³ to gal (UK) is 168.17856. Multiply your value by this number.
3. 3
   Read the result in UK gallons

   The result is your value in UK gallons (gal (UK)).

Multiply the value in cubic yards by 168.17856. For the reverse direction, multiply by 0.005946.

• ✓1 yd³ = 0.765 m³ = 27 ft³.
• ✓Concrete weighs about 2 tonnes per cubic yard — check truck capacity.
• ✓Some US soil suppliers sell by "yard" meaning cubic yard — clarify.

• ✗Confusing cubic yard with square yard or linear yard.
• ✗Assuming cubic yard = 1 m³ — off by 23%.
• ✗Ordering insufficient concrete by using ft³ instead of yd³.

What is the Cubic Yard?

The cubic yard equals exactly 27 cubic feet (or 0.764554857984 m³) and is the standard volume unit for American concrete delivery, mulch, topsoil, gravel, and bulk landscaping materials. Concrete is universally priced and ordered by the cubic yard in the US construction industry — a standard residential foundation might require 20–40 yd³, while a small driveway is around 3 yd³. The cubic yard is convenient for human-scale construction projects: a typical pickup truck bed holds about 2 yd³ of mulch. The cubic yard relates to the cubic foot (27 ft³ = 1 yd³), the cubic meter (1 yd³ ≈ 0.7646 m³), the gallon (1 yd³ ≈ 201.97 US gal), and the cubic inch (1 yd³ = 46,656 in³). Outside the United States and the United Kingdom, the cubic meter is dominant for the same purposes.

• Gravel, sand and soil delivery in the US
• US freight and waste-disposal volumes

What is the UK Gallon?

The UK imperial gallon equals exactly 4.54609 liters and is approximately 20% larger than the US gallon. Established by the British Weights and Measures Act of 1824 to standardize earlier ale and corn gallons, the imperial gallon was designed so that 10 pounds of pure water at 62°F occupied exactly 1 gallon. Although the United Kingdom has officially adopted the liter for fuel sales since 1995, the imperial gallon persists in everyday speech ('miles per gallon' for car fuel economy) and remains the standard unit in some Caribbean and Pacific Commonwealth countries. The imperial gallon relates to the US gallon (1 imp gal ≈ 1.201 US gal), the imperial quart (4 imp qt = 1 imp gal), the imperial pint (8 imp pt = 1 imp gal — the famous British pint of beer), and the liter (1 imp gal ≈ 4.546 L).

• Commonwealth countries that retain imperial measures
