How to Convert Cubic Foot to Quart Manually
Step by StepConverting cubic feet to quarts 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 29.922078The conversion factor from ft³ to qt is 29.922078. Multiply your value by this number.
- 3Read the result in quartsThe result is your value in quarts (qt).
Formula
Multiply the value in cubic feet by 29.922078. For the reverse direction, multiply by 0.03342.
qt = ft³ × 29.922078ft³ = qt × 0.03342Tips
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 Quart
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 Quart?
The US quart equals exactly one quarter of a US gallon (0.946352946 liters) and is a common kitchen and motor-oil volume in the United States. The word 'quart' derives from the Latin 'quartus' meaning fourth. Milk and motor oil are commonly sold in quart containers (a quart of motor oil is 32 fl oz), and large recipes call for quart-sized stockpots. The US quart is distinct from the slightly larger UK imperial quart (1.137 L). It relates to the gallon (4 qt = 1 gal), the pint (2 pt = 1 qt), the cup (4 cups = 1 qt), the fluid ounce (32 fl oz = 1 qt), and the liter (1 US qt ≈ 0.946 L). The quart is a useful intermediate volume between the cup (small recipe measurements) and the gallon (bulk liquids).
- US cooking recipe quantities
- US motor-oil container sizes (1 quart bottles)
- Canning and preserving containers
A US quart of motor oil is 946 ml. A "quart of milk" in the US ≈ 1 L. UK "quart" is rare today.
