Convert natural gas volume to therms for billing
Formula: Therms = Cubic Feet × BTU Factor × 0.00001
Note: 1 therm = 100,000 BTU. BTU content varies by gas source (typically ~1,031 BTU/cf).
| Cubic Feet | Therms |
|---|---|
| 50 | 0.52 |
| 100 | 1.03 |
| 200 | 2.06 |
| 500 | 5.16 |
| 1000 | 10.31 |
| 2000 | 20.62 |
| 5000 | 51.55 |
| 10000 | 103.10 |
Natural gas utilities measure consumption in various units. CCF (100 cubic feet) and therms are common. A therm represents 100,000 BTU of energy. Since natural gas has varying energy content depending on source, utilities apply a BTU factor to convert volume to energy for billing.
