Energy UnitsPuget Sound Energy (PSE) typically reports electricity use in kilowatt-hours while natural gas use is reported in therms. These units both convert into megajoules (MJ), which are used in the chart above to compare energy sources used by PSE's customers. The following conversion rates apply:
- 1 therm = 105.48 MJ
- 1 kilowatt-hour = 3.6 MJ
These conversion rates are estimates. The exact rates will vary based on energy source.
