Convert Cubic Meter to Cubic Foot (m³ → ft³)

Converting cubic meters to cubic feet 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 meters

   Start with the number of cubic meters (m³) you want to convert.
2. 2
   Multiply by 35.314667

   The conversion factor from m³ to ft³ is 35.314667. Multiply your value by this number.
3. 3
   Read the result in cubic feet

   The result is your value in cubic feet (ft³).

Multiply the value in cubic meters by 35.314667. For the reverse direction, multiply by 0.028317.

• ✓1 m³ = 1000 L = 1,000,000 ml.
• ✓A cube 1 m on each side contains 1 m³ — useful mental image.
• ✓Concrete for a small patio slab (3 × 3 × 0.1 m) = 0.9 m³.

• ✗Confusing m³ with m² (area) on architectural plans.
• ✗Using m³ when litres would communicate better for small volumes.
• ✗Mixing cubic metres and cubic feet without conversion — 1 m³ = 35.3 ft³.

What is the Cubic Meter?

The cubic meter equals exactly 1,000 liters and is the SI unit of volume, used for water utilities, construction materials, shipping containers, gas volumes, and industrial-scale measurements. Domestic water bills typically show consumption in cubic meters (a typical household uses 5–15 m³ per month), and natural-gas billing also uses m³. Concrete is delivered by the cubic meter, and shipping containers have internal volumes of about 33 m³ (20-ft) or 67 m³ (40-ft). The cubic meter is the volume of a cube measuring 1 meter on each side. It relates to the liter (1 m³ = 1,000 L), the cubic centimeter (1 m³ = 1,000,000 cm³), the cubic foot (1 m³ ≈ 35.31 ft³), and the US gallon (1 m³ ≈ 264.17 gal). Truck-cargo capacity, swimming-pool size, and natural-gas reserves are all commonly expressed in cubic meters.

• Household water and gas consumption on utility bills
• Concrete ordering for construction projects
• Shipping container and freight capacity

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).
