Convert dekatherms (Dth) to hundred cubic feet (Ccf), or solve for Dth, Ccf, or the Ccf-per-Dth conversion factor from two known values.

Use dekatherms and a Ccf-per-Dth factor.

Use a utility-specific factor on the same volume and heating-value basis. Energy-to-volume conversion has no universal fixed factor.

Use your utility’s factor; 1 Ccf is 100 ft³.

Dth To Ccf Formula

The following equation converts dekatherms to Ccf using a factor appropriate for the gas and utility volume basis. There is no universal fixed energy-to-volume factor.

Ccf = Dth × CF
  • Where Ccf is the Hundred Cubic Feet
  • Dth is the Dekatherms
  • CF is the Conversion Factor (Ccf per Dth)

To convert Dekatherms to Hundred Cubic Feet, multiply the Dekatherms by the Conversion Factor.

*Assumes higher heating value of natural gas ≈ 1,030 BTU/scf. With 1 Dth = 1,000,000 BTU and 1 Ccf = 100 scf, this yields 1 Dth ≈ 9.7087 Ccf. Actual factors vary by utility and gas composition.

What is a Dth to Ccf Conversion?

Definition:

The Dth to Ccf conversion is used in natural gas measurements, where Dekatherms quantify energy and Hundred Cubic Feet measure volume. The Conversion Factor indicates how many Hundred Cubic Feet are equivalent to one Dekatherm.

How to Calculate Dth to Ccf?

Example Problem:

The following example outlines the steps and information needed to perform the conversion.

First, determine the amount of Dekatherms. In this example, assume you have 5 Dekatherms.

Next, determine the Conversion Factor. For this example, use an assumed factor of 10 Ccf per Dth and select Ccf volume mode. This factor corresponds to 1,000 Btu/ft³ on the same volume basis.

Finally, calculate the Hundred Cubic Feet using the formula above:

Ccf = Dth * CF

Ccf = 5 * 10

Ccf = 50 Hundred Cubic Feet

FAQ

What units are used in this conversion?

Dekatherms measure energy content while Hundred Cubic Feet measure volume, with the Conversion Factor relating the two.

How does the calculator determine the missing value?

Select Ccf volume, Dekatherms or Conversion factor. The calculator applies the corresponding formula to the two displayed inputs.

What should I do if all fields are filled?

Select the value to solve for and enter the two displayed values. Known-factor conversions allow zero quantities; inferring a positive factor requires positive Dth and Ccf quantities.
