About Microwatt per square metre
The microwatt per square metre (µW/m²) equals 10⁻⁶ W/m². Encountered in geothermal science - deep crustal heat flux measurements in stable shield regions can reach a few µW/m² - and in bio-electromagnetic research for very low intensity radiation fields. 1 µW/m² = 10⁻⁶ W/m² = 10³ nW/m².
About International table BTU per hour per square inch
The international table BTU per hour per square inch (BTU(IT)/(h·in²)) equals 1055.05585262/(3600×6.4516×10⁻⁴) ≈ 454.26 W/m². Used for high heat flux applications such as electronic component cooling, jet engine combustor walls, and nuclear fuel assembly design in US customary units. 1 BTU(IT)/(h·in²) ≈ 454.26 W/m².
