How to Convert Cubic Foot to Cubic Yard Manually
Step by StepConverting cubic feet to cubic yards is straightforward: multiply by the conversion factor. Follow these three steps to do it by hand or in your head.
- 1Take your value in cubic feetStart with the number of cubic feet (ft³) you want to convert.
- 2Multiply by 0.037037The conversion factor from ft³ to yd³ is 0.037037. Multiply your value by this number.
- 3Read the result in cubic yardsThe result is your value in cubic yards (yd³).
Formula
Multiply the value in cubic feet by 0.037037. For the reverse direction, multiply by 27.
yd³ = ft³ × 0.037037ft³ = yd³ × 27Tips
Use these in everyday conversions- 1 ft³ = 28.317 L = 0.0283 m³.
- CFM to m³/h: multiply CFM by 1.699.
- 1 m³ ≈ 35.3 ft³.
Common Mistakes
Avoid these- Confusing ft³ with ft² in US real-estate contexts.
- Using 28 L instead of 28.32 L in precision HVAC calculations.
- Mixing CCF (100 cubic feet) with CFM (cubic feet per minute) on utility bills.
About Cubic Foot and Cubic Yard
What is the Cubic Foot?
The cubic foot equals approximately 28.317 liters (or exactly 1,728 cubic inches) and is the American standard volume unit for HVAC capacity, natural-gas billing, refrigerator interior volume, and bulk material like concrete or mulch. American gas utilities measure delivered gas in 'CCF' (hundred cubic feet) or 'MCF' (thousand cubic feet), even when the customer thinks in terms of monthly bills. Refrigerators are advertised by their interior cubic-foot capacity (typical home unit: 18–25 ft³). Air-conditioning systems are rated in CFM (cubic feet per minute) airflow. Concrete is sometimes priced by the cubic yard (27 ft³), and mulch and topsoil are often sold by cubic foot bags. The cubic foot relates to the cubic yard (27 ft³ = 1 yd³), the cubic inch (1,728 in³ = 1 ft³), the cubic meter (1 ft³ ≈ 0.0283 m³), and the gallon (1 ft³ ≈ 7.481 US gal).
- US air-conditioning and ventilation flow (CFM)
- US natural gas consumption
- Refrigerator and freezer capacity in the US
A typical US fridge is 20 cu ft (566 L). US HVAC flow rated in CFM. US residential gas billed per 100 cu ft (CCF).
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.
- Concrete ordering for US construction
- Gravel, sand and soil delivery in the US
- US freight and waste-disposal volumes
A residential US concrete pour might need 3–8 cubic yards. US garbage dumpsters rated in cubic yards.
