kW to MMBtu Formula

The following formulas convert kW to MMBtu/h (power) and kWh to MMBtu (energy) using the International Table Btu.

\mathrm{MMBtu/h} = 3.412141633\times 10^{-3}\,\mathrm{kW}
  • 1 Wh = 3.412141633 Btu (IT)
  • 1 Btu/h ≈ 0.29307107 W; 1 W = 3.412141633 Btu/h
  • 1 kW = 0.003412141633 MMBtu/h = 3,412.141633 Btu/h
  • 1 kWh = 0.003412141633 MMBtu; 1 MMBtu = 293.07107 kWh
