About these measurements
Heat flux is thermal power per unit surface area.
The base reference used here is the watt per square meter. One kilowatt per square meter is 1,000 base units; one it btu per hour square foot is 3.154590745 base units.
Important distinctions
Compound units must match the quantity and dimension. Temperature intervals use size factors rather than temperature offsets. Calorie and BTU entries use the explicit definitions shown.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
