\"M\" in MBH

If MBH = Thousands of BTUs Per Hour - why is an "M" used to represent 1,000 instead of "K" (kilo)?

Thanks...

    It predates adoption of the modern metric system

    Something about using old terminology. Traditions change hard.

    Keep in mind; 50 years ago their were very few countries that used the metric system. 100 years ago almost none. The inch system was standard in much of the world 100 years ago' although I do not know what system was used in the far east then - certainly not the French based metric system.

    \" M \"

    From the roman numerial system "M" means Thousand. At least thats my explanation.

    Yes, it's from Roman numerals where "M" = 1,000

    "M" is still used in printing as well.
