Calculate SCF from CCF or CCF from SCF for natural gas, with optional meter pressure and temperature correction plus therms, BTU, MMBtu, kWh and cost.
Ccf To Scf Conversion Formula
The following equation converts between Ccf and Scf when both volumes refer to the same base pressure and temperature. For an uncompensated meter at line conditions, enable pressure and temperature correction in the calculator.
- Where SCF is the standard cubic feet
- CCF is the hundred cubic feet
- 100 is the conversion factor between CCF and SCF
At matching base conditions, multiply Ccf by 100 or divide Scf by 100. When correction is enabled, SCF = metered Ccf × 100 × (absolute line pressure / base pressure) × (519.67 / gas temperature in °R) × Fpv². Absolute line pressure is gauge plus atmospheric pressure; the base temperature is 60 °F. Use the utility’s base pressure and supercompressibility factor.

What are Ccf and Scf?
Definition:
Ccf stands for hundred cubic feet and is a unit used for measuring large volumes in industries such as natural gas distribution, while Scf stands for standard cubic feet and represents the volume of gas at standard temperature and pressure conditions.
How to Convert Between Ccf and Scf?
Example Problem:
The following example outlines the steps and information needed to convert between Ccf and Scf.
First, determine the value to convert. In this example, assume you have 5 Ccf.
Select SCF from Ccf, enter 5 Ccf, and leave meter correction off when the input is already at the same base conditions. Select Calculate.
The result is 500 SCF at matching base conditions. Reverse mode divides standard volume by 100, or also divides by the entered meter correction factor when enabled.
SCF = CCF × 100
SCF = 5 × 100
SCF = 500
FAQ
What is the difference between Ccf and Scf?
Ccf is a unit representing one hundred cubic feet, often used for large-scale volume measurements, whereas Scf denotes the volume of gas at standard conditions.
Why is the conversion factor 100?
By definition, one Ccf is equivalent to 100 Scf under standard conditions, which is why the conversion factor is 100.
Can this calculator be used for other conversions?
The calculator also solves volume from billed energy using the entered heating value, and reports energy equivalents and optional cost. The heating-value default of 1,037 BTU/SCF is illustrative; use the HHV on your bill. Optional combustion COâ‚‚ uses the EPA 2025 natural-gas factor of 53.06 kg/MMBtu on an HHV basis and excludes upstream emissions.
