Frequently Asked Questions
- What does degree Fahrenheit hour per Btu (IT) measure?
- It measures thermal resistance representing the temperature difference in degrees Fahrenheit caused by a heat flow of one Btu per hour, using the International-Table Btu definition.
- Where is kelvin per watt (K/W) commonly used?
- Kelvin per watt quantifies thermal resistance in thermal-circuit models and is commonly used to specify junction-to-ambient or junction-to-case resistances for electronic components.
- Why convert between these two units?
- Converting allows users to reconcile thermal resistance values between U.S. customary units and SI units for accurate thermal network modeling and performance comparison.
