-
Convert 5 calorie (th)/hour/square centimeter: 5 × 0.0614448431 = 0.3072242155 Btu (th)/minute/square foot.
Common Use Cases
-
Relating small-area heat flux measurements in laboratory calorimetry to HVAC standard units.
-
Comparing heat transfer rates for material or coating thermal tests.
-
Specifying heat exposure levels in fire testing and building insulation evaluations.
-
Assessing heat loss or gain in building components for HVAC load calculations.
Tips & Best Practices
-
Ensure consistency in the units used for area and time during measurement and conversion.
-
Review historical unit standards carefully when working with calorie-based units.
-
Use this tool to bridge older measurement systems with modern engineering standards.
-
Check the uniformity of heat flux distribution for accurate interpretation.
Limitations
-
Differences in area units (square centimeters versus square feet) and time units (hour versus minute) require precise attention.
-
Calorie-based units from older standards may be less precise than SI units.
-
Interpretation depends on how uniformly heat flux is distributed on the surface measured.
