CNG
| 1 Cubic Foot = 1,000 BTU (typical value) |
| 100 Cubic Feet = 1C cubic feet = 0.1M cf = 1 Therm = 100,000 BTU |
| 1 mmBTU = 1,000,000 BTU = 10 Therms = 1 dth (dekatherm) = 1 mcf |
| 1 Therm = 100,000 BTU |
| 1.25 Therms = 1 GGE = 1 CNG Gallon = 125,000 BTU |
| 1.39 Therms = 1 DGE = 139,000 BTU |
| 8 GGE = 1 mmBTU |
| 1 GGE = 125 standard cubic feet (scf) |
LNG
| 1 LNG Gallon = 82,000 BTU |
| 1 DGE = 139,000 BTU |
| 1.7 LNG Gallons = 1 DGE (139k/82k) |
| 1.5 LNG Gallons = 1 GGE (125k/82k) |
| 12.2 LNG Gallons = 1 mmBTU |
| 7.19 DGE = 1 mmBTU (1mm / 139k) |
| 10 LNG Gallons = 5.9 DGE (10/1.7) |
| 1 DGE = 139 scf |
