How it works

Enter an amount and choose its unit to see it in every common oil and gas energy unit. Btu is the International Table Btu (1 055.056 J) and 1 MMBtu is one million Btu.

Formula

1 MMBtu = 1.05506 GJ = 293.071 kWh

Assumptions and limits

boe and toe are conventions, not physical constants: this tool uses 1 boe = 6.1178632 GJ and 1 toe = 41.868 GJ, and companies and agencies use slightly different values. Use the figure your reporting standard specifies.

For education and quick estimates only. Check the result against the applicable standards and your project data before using it in design, operation or safety decisions.
