What does Btu (IT)/minute/square foot measure?

It measures the rate of heat transfer per unit area, specifically one International Table British thermal unit transferred per minute through one square foot.

Why convert Btu (IT)/minute/square foot to watt/square meter?

Converting to watt/square meter allows heat flux density values to align with the SI unit system, facilitating compatibility with modern instrumentation, international standards, and scientific research.

Can this conversion be used for transient heat flux data?

No, this tool assumes steady-state conditions. Transient or variable heat flux requires more complex modeling beyond simple unit conversion.
