What does Btu (th)/second/square foot measure?

It measures the rate of heat transfer per unit area, representing one British thermal unit of energy transferred per second across one square foot.

When should I use Calorie (th)/second/square centimeter?

This unit is useful in laboratory calorimetry, fire testing, and when working with legacy data or small-scale heating measurements.

Why convert between these two units?

Conversion helps align measurements from Imperial to legacy metric units for consistent heat flux reporting and comparisons across systems and historical data.
