CarbonKit supports the use of several versions of the Btu. See here for details on how to specify these units.
There is some ambiguity around the specification of multiples of the British Thermal Unit (Btu), with the prefixes 'M-', and 'MM-' (or 'mm-') both commonly used to represent a factor of a million. In some cases, owing to the legacy of Roman numerals, the 'M-' prefix is also used to describe a factor of one thousand.
Given these ambiguities, users wishing to use the Btu as their unit of energy specification should familiarise themselves with the specifications for multiple Btu's which are valid when using the CarbonKit platform and associated tools. CarbonKit uses standard SI prefixes, and, as such, the following are appropriate when using Btu's:
- k = x 1 000
- M = x 1 000 000
- G = x 1 000 000 000
- T = x 1 000 000 000 000
- MM = x 1 000 000
Users can, of course, specify energy consumption in kilowatt-hours or joules (or multiples thereof; e.g. MWh, GJ, etc.)
