Heat flux density (Q) is calculated using the formula:

Q=PowerAreaQ = \frac{Power}{Area}


  • QQ = Heat flux density (in the desired unit)
  • PowerPower = Heat transfer rate (in watts or its equivalent)
  • AreaArea = Area over which heat transfer occurs (in square meters or its equivalent)

How to Convert:

To convert between different units of heat flux density, follow these steps:

  1. Identify the unit you have and the unit you want to convert to.
  2. Determine the conversion factor between the two units. This factor may involve simple multiplication or division.
  3. Multiply or divide the heat flux density value by the conversion factor to obtain the equivalent value in the desired unit.


  1. Conversion from Watt/square meter to Kilowatt/square meter:Conversion Factor: 1 kilowatt = 1000 watts1W/m2=11000kW/m21 \, \text{W/m}^2 = \frac{1}{1000} \, \text{kW/m}^2

  2. Conversion from Joule/second/square meter to Btu (IT)/hour/square foot:Conversion Factor: 1 Btu (IT) = 1055.06 joules, 1 hour = 3600 seconds, 1 square foot = 0.092903 square meters1J/s/m2=1055.06×36000.092903Btu (IT)/h/ft21 \, \text{J/s/m}^2 = \frac{1055.06 \times 3600}{0.092903} \, \text{Btu (IT)/h/ft}^2

  3. Conversion from Calorie (IT)/minute/square centimeter to Dyne/hour/centimeter:Conversion Factor: 1 calorie (IT) = 4.184 joules, 1 dyne = 0.00001 newtons, 1 minute = 60 seconds1cal (IT)/min/cm2=4.184×600.00001dyn/h/cm1 \, \text{cal (IT)/min/cm}^2 = \frac{4.184 \times 60}{0.00001} \, \text{dyn/h/cm}

By following these steps, you can accurately convert between various units of heat flux density, facilitating efficient communication and analysis in fields where heat transfer plays a critical role.
