Potential rounding errors if unit differences are oversimplified
Frequently Asked Questions
-
What does foot pound/minute/square foot measure?
-
It is a heat flux density unit indicating the rate of energy transfer per unit area using imperial energy and area units.
-
Why convert to calorie (th)/hour/square centimeter?
-
Because calorie (th)/hour/square centimeter is commonly used in calorimetric tests and older engineering contexts focusing on small-area heat flux measurements.
-
Can this conversion be used for transient heat flux?
-
No, this conversion is best suited for steady-state heat flux. Dynamic or transient heat flux requires more complex models.
Key Terminology
