How to Convert TMC to Cubic Kilometre
- 1 TMC = 0.02831684659 km³
- 1 km³ = 35.31466672 TMC
- Example: convert 15 TMC to km³: 15 TMC = 15 × 0.02831684659 km³ = 0.4247526989 km³
Formula
km³ = TMC × 0.028316846592
or km³ = TMC ÷ 35.31466672149
Derivation from SI units:
- 1 TMC = 10⁹ ft³ = 28.316846592 MCM.
- 1 km³ = 10⁹ m³ = 1 BCM.
- 1 TMC = 28.316846592 MCM ÷ 1000 MCM per km³ = 0.028316846592 km³
Both units are defined exactly, so the factor is exact. TMC definition: TMC; Cubic Kilometre definition: cubic kilometre.
Worked examples
- A reading of 10 TMC converts to 0.2831684659 km³.
10 TMC × 0.02831684659 = 0.2831684659 km³ - A value of 100 TMC is 2.831684659 km³.
100 TMC × 0.02831684659 = 2.831684659 km³
