In radiometry, irradiance is the radiant flux received by a surface per unit area. The SI unit of irradiance is the watt per square metre (W⋅m −2). The CGS unit erg per square centimetre per second (erg⋅cm −2 ⋅s −1) is often used in astronomy.
Conversion of units of measurement from physics and maths, e.g. Intensity - Watt per square metre [W/m²]
Solar irradiance is the power per unit area (surface power density) received from the Sun in the form of electromagnetic radiation in the wavelength range of the measuring instrument. Solar irradiance is measured in watts per square metre (W/m 2) in SI units.
The watt per square meter (W/m^2) is a unit of measurement that represents the rate of energy transfer or power per unit area. It is commonly used to quantify the intensity or flux of various forms of radiation, including sound waves, in the context of physics and engineering.
Irradiance (or flux density) is a term of radiometry and is defined as the radiant flux received by some surface per unit area. In the SI system, it is specified in units of W/m 2 (watts per square meter). Irradiance may be applied to light or other kinds of radiation.
W/m 2: heat flux density, irradiance: kg s −3: The watt per square metre, symbol W/m 2, is the SI coherent derived unit of heat flux density, and irradiance. Definition: h c −2 Δν Cs 4
The SI unit of radiance is watts per square meter per steradian [W/m2-sr]. Since many radiation sources used in laboratories have emitting area in the square millimeters range, the unit of milliwatts per square millimeter per steradian [mW/mm2-sr] is often used for radiance.
