What does gram/calorie (IT) measure?

Gram/calorie (IT) measures mass per unit of thermal energy, indicating how many grams are needed to deliver one International‑Table calorie of energy.

Why convert gram/calorie (IT) to Btu (th)/pound?

This conversion helps translate mass-based fuel efficiency values into more commonly used thermochemical British thermal units per pound for easier comparison and engineering use.

Are the calorie definitions used in this converter the same as all other calorie units?

No, the International‑Table calorie differs slightly from other calorie definitions, which can lead to minor differences in conversion results.

What Is This Tool?

This converter transforms values from gram/calorie (IT), a unit expressing mass per unit of energy based on the International-Table calorie, into Btu (th)/pound, a unit measuring thermal energy per pound of material using the thermochemical British thermal unit.

How to Use This Tool?

Enter the value in gram/calorie (IT) unit you wish to convert
Select 'gram/calorie (IT) [g/cal]' as the input unit
Choose 'Btu (th)/pound [Btu (th)/lb]' as the output unit
Click convert to get the equivalent value in Btu (th)/lb
Use the result for fuel comparison, system design, or reporting

Key Features

Converts mass-based fuel efficiency values from g/cal (IT) to Btu (th)/lb
