Cubic Feet to Cubic Meter (CFT to CUM)
Updated
1 cubic foot = 0.0283168 cubic metre, and 1 cubic metre = 35.3147 cubic feet. Sand, aggregate and concrete are ordered in cft (or brass) but designed and billed in cubic metres (cum) — convert between them, and to brass and litres, below.

How the conversion works
One foot is 0.3048 metre, so one cubic foot is 0.3048³ = 0.0283168 cubic metre. Going the other way, one cubic metre holds 35.3147 cubic feet:
m³ = cft ÷ 35.3147 · cft = m³ × 35.3147
One brass is 100 cubic feet = 2.83168 cubic metres — the standard truck-load measure for sand and aggregate. See the brass converter for that unit in full.

Where you use it
A tempo of sand quoted as "100 cft" is one brass, or 2.83 m³. Concrete and RCC quantities from a design come in m³ — turn them into cft to order aggregate, or use the concrete calculator and volume calculator which report both.
Frequently asked questions
How many cubic feet are in 1 cubic meter? One cubic metre equals 35.3147 cubic feet. Multiply any cubic-metre figure by 35.3147 to get cubic feet.
How do I convert cubic feet to cubic meter? Divide the cubic-feet value by 35.3147, or multiply by 0.0283168. For example, 100 cft ÷ 35.3147 = 2.832 m³.
How many cubic feet is 1 brass? One brass is 100 cubic feet, which equals 2.832 cubic metres. Brass is the usual unit for ordering sand and aggregate by the truck.
How many cubic meters is 100 cft of sand? 100 cubic feet is 2.832 cubic metres. That is also exactly one brass.
