## How many cubic feet are in a BTU?

In 2020, the U.S. annual average heat content of natural gas delivered to consumers was about 1,037 Btu per cubic foot. Therefore, 100 cubic feet (Ccf) of natural gas equals 103,700 Btu, or 1.037 therms. One thousand cubic feet (Mcf) of natural gas equals 1.037 MMBtu, or 10.37 therms.

**How do I convert cubic feet of natural gas to BTU?**

Natural gas: 1 cu ft of natural gas = 1,030 Btu.

**What is the BTU heat of 1 cubic foot of natural gas?**

1,037 Btu

Sample Btu conversion factors

Energy source/fuel | Physical units and Btu1 |
---|---|

Natural gas | 1 cubic foot = 1,037 Btu 1 therm = 100,000 Btu |

Motor gasoline | 1 gallon = 120,286 Btu2 |

Diesel fuel | 1 gallon = 137,381 Btu3 |

Heating oil | 1 gallon = 138,500 Btu4 |

### How many BTU does it take to heat a cubic foot of air?

It takes 0.24 BTU of heat to change the temperature of one pound of air by one degree F. The 1.08 factor also contains the specific density of air (0.075 pounds per cubic foot). The air is measured in CFM, yet the specific heat is per pound of air.

**How do you calculate BTU heat?**

For example, a 300 square foot room typically requires 7,000 BTUs to maintain a comfortable temperature, while a 1,000 square foot room requires 18,000 BTUs. A simple formula to determine your heating needs is: (desired temperature change) x (cubic feet of space) x . 133 = BTUs needed per hour.

**How do you calculate BTU of gas?**

Computing BTUH: Technical Note: you can compute the BTU’s per hour of gas consumption of your gas-fired equipment. Making sure than only a single gas appliance is running, watch the gas meter and measure the time required to use one cubic foot of gas. The formula: (3600 x 1000)/seconds = BTUH.

#### How many cubic feet is 1 MMBtu?

The answer is: 1 mmBTU equals 1,000.00 cu ft N.G.
