Imperial Fluid Ounces to Cubic Yards (fl oz (UK) to yd³)

1 imperial fluid ounce equals 0.00003716288269 cubic yards (rounded).

1 imperial fluid ounce = 0.00003716288269 cubic yards

How to convert imperial fluid ounces to cubic yards

To convert imperial fluid ounces to cubic yards, multiply the number of imperial fluid ounces by 0.00003716288269. The factor is rounded to 10 significant digits. To go the other way, multiply cubic yards by 26,908.56918 (rounded).

cubic yards = imperial fluid ounces × 0.00003716288269

Example: 10 imperial fluid ounces = 0.0003716288269 cubic yards.

Pints, quarts, gallons and fluid ounces differ between the US and the UK. Units are labeled 'US' or 'imperial' to avoid confusion.

About these units

Imperial Fluid Ounce (fl oz (UK))

Imperial (British)Current unit

Exactly 28.4130625 mL. About 4% smaller than the US fluid ounce.

Imperial fluid ounce comes from the 1824 reform that defined the British gallon as the volume of ten pounds of water. Because a gallon was set at 160 fluid ounces, an ounce of water weighs about one ounce of mass, around 28.35 grams. That neat link between volume and weight was the point of the imperial scheme, and it explains why people long thought of fluid ounces and weight ounces as nearly the same.

Today an imperial fluid ounce is exactly 28.4130625 milliliters, one twentieth of an imperial pint. That is about 4 percent smaller than the US fluid ounce at 29.57 mL, so a US recipe using fluid ounces does not map one-for-one onto a British one. UK trade rules restricted its use in 1995, and it lives on mostly on older labels, in bars and in recipes. Twenty of them fill an imperial pint, which makes the pint the easiest way to picture one.

1 imperial fluid ounce = 0.0284130625 liters (exactly).

Cubic Yard (yd³)

US & ImperialCurrent unit

27 cubic feet or 764.555 liters. Used for soil, gravel and concrete in the US.

Cubic yard is a cube three feet on each side, which makes it exactly 27 cubic feet or 46,656 cubic inches. In metric terms it is about 0.7646 cubic meters, or 764.55 liters. The unit follows the yard in the United States and Canada, and British railways once rated ballast wagons by it, with one Great Western Railway wagon holding 8 cubic yards.

A cubic yard is easier to picture than the number suggests. It holds about 202 US gallons, or nearly five oil barrels. That is a scale where bulk materials such as soil, gravel, mulch and concrete are naturally counted, so a patio slab or garden bed needs a handful of them. A handy rule of thumb follows from the arithmetic: one cubic yard spread one inch deep covers 324 square feet.

1 cubic yard = 764.554858 liters (approximately).
