  • Confusing the International Table Btu with the thermochemical Btu can cause errors in assessments.

Frequently Asked Questions

Why are there two different Btu units for thermal conductivity?
They represent different definitions of the British thermal unit used in US customary engineering, impacting thermal conductivity calculations.

Can I use this converter for SI unit conversions?
This converter specifically handles conversion between two US customary units; further conversion to SI units requires other tools.

Is the conversion factor exactly 1 to 1?
No, the conversion factor is very close to one but slightly different, which can influence precision in sensitive calculations.

Key Terminology

Btu (IT) inch/second/sq. foot/°F
A thermal conductivity unit representing heat flow in British thermal units based on the International Table definition through a one-inch thick, one square foot area for a one degree Fahrenheit temperature difference.
Btu (th) inch/second/sq. foot/°F
An Imperial US customary thermal conductivity unit using the thermochemical British thermal unit definition, measuring heat transferred per second through a one-inch thickness over one square foot area per degree Fahrenheit.
