About Cubic Feet
The cubic feet is the volume of a cube one feet on a side (about 28.3168 liters). HVAC, construction, and US freight sometimes use cubic feet.
About Cubic Meter
The cubic meter is the SI-derived unit of volume. One cubic meter equals 1,000 liters. Engineering, shipping containers, and scientific volumes often use m³.
How to convert cubic feet to cubic meters
1 cubic feet is equal to 0.028316846592 cubic meter:
1 ft3 = (28.316846592 L ÷ 1000 L) m3 = 0.028316846592 m3
Each cubic feet is defined as 28.316846592 L and each cubic meter as 1000 L, so one ft3 equals 28.316846592 ÷ 1000 m3 = 0.028316846592 m3.
Let V(ft3) be the numeric value of the same volume measured in Cubic Feet (ft3), and V(m3) the value in Cubic Meter (m3). Then:
V(m3) = V(ft3) × (28.316846592 / 1000)
Equivalently, divide by how many ft3 fit into one m3 (liters per m3 divided by liters per ft3):
V(m3) = V(ft3) ÷ 35.31466672148859
Or: cubic meter = cubic feet ÷ 35.31466672148859
Examples
Example #1: Convert 20 ft3 to cubic meter
20 ft3 = 20 ft3 × (28.316846592/1000) m3 = 0.5663369318 m3
20 ft3 = 20 ft3 ÷ 35.31466672148859 = 0.5663369318 m3
Example #2: Convert 50 ft3 to cubic meter
50 ft3 = 50 ft3 × (28.316846592/1000) m3 = 1.4158423296 m3
50 ft3 = 50 ft3 ÷ 35.31466672148859 = 1.4158423296 m3
Summary
To convert Cubic Feet to Cubic Meter, multiply the value in ft3 by the ratio of liters per ft3 divided by liters per m3. Equivalently: value_m3 = value_ft3 × (28.316846592 / 1000). Numerically, 1 ft3 equals 0.028316846592 m3.
Relationship context
You are converting between US customary fluid / volume (Cubic Feet) and metric (SI) (Cubic Meters). US and UK fluid measures differ (gallons, ounces, tablespoons); metric liters and cubic meters align with SI. The numeric factor used here is 2.831685e-2.
