Does the "M" mean "Million" or "Thousand (Mcf/Mlbs/MWh/MBtu)?" Follow

Portfolio Manager uses "M" to represents million (Mcf =Million Cubic Feet) and "k" to represents thousand. However, some utilities use M to represent "thousand" and M to represent "million."  Unfortunately, there isn't an industry standard on this term.

We chose our approach (M= million, k=thousand) because: 

  • We needed to pick one standard for consistency.  We couldn't have the "M" stand for thousand in Mcf and the "k" stand for thousand in kBtu.
  • The metric system is the international standard:
    c=100 K=1,000 M=1,000,000

Because we know utilities use both conventions to express 1,000 (kcf and Mcf), we always show the written out equivalent when you select units:

kcf

Thousand cubic feet

Mcf

Million cubic feet

klbs Thousand pounds
Mlbs Million pounds
 kWh Thousand Watt hours
 MWh  Million Watt hours
 kBtu  Thousand Btu
 MBtu  Million Btu
