About Cubic foot (ft³)
A cubic foot (ft³) is the volume of a cube with 1-foot sides, equal to approximately 28.317 liters or 7.48 US gallons. It is used in the United States for natural gas billing, refrigerator capacity, aquarium size, concrete orders, and shipping container dimensions. Refrigerators are rated in cubic feet of storage, natural gas consumption is billed in cubic feet, and HVAC airflow is measured in cubic feet per minute (CFM).
A full-size refrigerator is typically 18–28 ft³. Natural gas is billed in CCF (hundreds of cubic feet) in the US.
About Cubic meter (m³)
The cubic meter (m³) is the SI derived unit of volume, defined as the volume of a cube with sides of exactly one meter. It is the standard unit for large-volume measurement in science, engineering, construction, and trade. One cubic meter equals 1,000 liters. Natural gas is sold by the cubic meter, concrete is ordered in m³, swimming pools and shipping containers are described in cubic meters, and HVAC airflow is measured in m³/hour.
A standard bathtub holds about 0.15–0.2 m³. A 20-foot shipping container has an internal volume of roughly 33 m³.
Cubic foot – Frequently Asked Questions
How many liters are in a cubic foot?
One cubic foot equals approximately 28.317 liters. Since 1 foot = 30.48 cm, 1 ft³ = 30.48³ cm³ = 28,316.8 cm³ = 28.317 liters.
Why is natural gas measured in cubic feet in the US?
The US gas industry adopted cubic feet before metrication became widespread. Natural gas is billed in CCF (hundred cubic feet) or therms (≈ 100 ft³ by energy content). Metric countries use cubic meters.
What does cubic feet mean for refrigerators?
Refrigerator capacity is rated in cubic feet of internal storage. A compact dorm fridge is 1–4 ft³; a standard family fridge is 18–22 ft³; a large French door model can exceed 28 ft³.
What is CFM (cubic feet per minute)?
CFM measures volumetric airflow rate. HVAC systems, range hoods, and fans are rated in CFM. A typical home range hood requires 100–600 CFM; a whole-home HVAC system might move 2,000 CFM.
How many US gallons are in a cubic foot?
One cubic foot equals approximately 7.48 US liquid gallons. This is commonly used in plumbing, aquarium sizing, and pool volume calculations.
Cubic meter – Frequently Asked Questions
How many liters are in a cubic meter?
There are exactly 1,000 liters in one cubic meter. This follows from 1 m³ = 1,000 dm³ and 1 dm³ = 1 liter.
Why is natural gas measured in cubic meters?
Natural gas is billed by volume at standard conditions. The cubic meter is the standard billing unit in most metric countries. In the US, natural gas is sold in cubic feet instead.
How big is one cubic meter?
Imagine a cube one meter on each side — about the size of a large washing machine. It holds 1,000 liters of water, which weighs exactly 1,000 kg (one metric tonne) at standard conditions.
What is a cubic meter used for in construction?
Concrete is ordered and priced by the cubic meter. A typical residential house slab might use 10–20 m³ of concrete. Excavated soil, fill material, and gravel are also sold per cubic meter.
How does m³/h relate to airflow?
Cubic meters per hour (m³/h) measures volumetric airflow rate — common in HVAC, ventilation, and industrial fan specifications. A domestic kitchen extractor fan typically moves 200–600 m³/h. The imperial equivalent is cubic feet per minute (CFM).
