How to Convert Hectare-metre to TMC
- 1 ha·m = 0.0003531466672 TMC
- 1 TMC = 2831.684659 ha·m
- Example: convert 15 ha·m to TMC: 15 ha·m = 15 × 0.0003531466672 TMC = 0.005297200008 TMC
Formula
TMC = ha·m × 0.0003531466672149
or TMC = ha·m ÷ 2831.6846592
Derivation from SI units:
- 1 ha·m = 10,000 m² × 1 m = 10⁴ m³ = 0.01 MCM.
- 1 TMC = 10⁹ ft³ = 28.316846592 MCM.
- 1 ha·m = 0.01 MCM ÷ 28.316846592 MCM per TMC = 0.0003531466672149 TMC
Both units are defined exactly, so the factor is exact. Hectare-metre definition: hectare-metre; TMC definition: TMC.
Worked examples
- A reading of 100 ha·m converts to 0.03531466672 TMC.
100 ha·m × 0.0003531466672 = 0.03531466672 TMC - A value of 5000 ha·m is 1.765733336 TMC.
5000 ha·m × 0.0003531466672 = 1.765733336 TMC

Where it's used
Hectare-metres are used for crop water requirement and duty–delta problems, while TMC appear in cauvery, Krishna and Godavari tribunal awards. Both measure volume of stored or released water (reservoirs, river flows, allocations), so the conversion is a fixed factor.

Frequently asked questions
How many TMC are in 1 hectare-metre?
1 ha·m = 0.0003531466672 TMC.
How do I convert hectare-metres to TMC?
Multiply the value in ha·m by 0.0003531466672, or divide it by 2831.684659. For example, 15 ha·m × 0.0003531466672 = 0.005297200008 TMC.
Is the ha·m to TMC conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
