Conversion for btu from kwh?

Question

okay so I have something that produced 419,777 kwh. I need that in mbtu how would i do that? Please!

Answer 1

419,777 kwh (do you really know it to 6 digits? I don't think even the NBS can measure energy that accurately!)

419,777 kwh is 1432338000 BTU

mBTU is a rarely used unit, it is 1000 BTU

1432338000 BTU = 1432338000000 mBTU

  = 1432338000000000  mmBTU

or maybe you are being sloppy with your prefixes and mean MBTU

1432338000 BTU = 1432338 MBTU

MMBTU is never used, perhaps you mean TBTU (tera BTU)?

1432338000 BTU = 1.432338 TBTU

.

Answer 2

1 kilowatt = 3412.141633128 Btu (IT)/hour

therefore 1 kwhr = 3412.1416 Btu

therefore in our case we get 1,432,338,578.3295 BTU

equalling: 1432.34 MBtu

Answer 3

1 btu = 1.055 056 E^3 W/s
