How do I convert data in one unit of measure to a different unit of measure?
We offer resources for converting data for energy, fuels, and electricity in physical units to heat content equivalents. EIA also offers resources for converting English units to metric units:
- Energy conversion calculators
- Heat content and metric conversion factors
- Unit of measure equivalents for electricity
EIA usually publishes petroleum data in physical units such as barrels or barrels per day. Barrels per day are calculated as the total number of barrels (produced, imported, exported, or consumed) during a calendar period (week, month, or year) divided by the number of days in the calendar period. There are 42 U.S. gallons in a barrel.
