Can someone explain to me the unit MMbtu/hr?

Question

Answer 1

BTU/hr is a unit of power, equal to 0.293 watts

M is the standard SI prefix for 10^6 or x 1000000

Use of MM is not NOT to SI standards

As you can see, there are various definitions:

Dictionaries:

MBTU stands for one million BTUs

MBTU is occasionally expressed as MMBTU, which is intended to represent a thousand thousand BTUs.

MMBtu One million British thermal units

MMBtu -- One million British thermal units.
