Description

$Watt per steradian per square metre$ is the SI unit of radiance ( $W \cdot s r^{- 1} \cdot m^{- 2}$ ), while that of spectral radiance in frequency is the watt per steradian per square metre per hertz ( $W \cdot s r^{- 1} \cdot m^{- 2} \cdot H z^{- 1}$ ) and that of spectral radiance in wavelength is the watt per steradian per square metre, per metre ( $W \cdot s r^{- 1} \cdot m^{- 3}$ ), commonly the watt per steradian per square metre per nanometre ( $W \cdot s r^{- 1} \cdot m^{- 2} \cdot n m^{- 1}$ ). It has a dimension of $M L^{- 4} T^{- 3}$ where $M$ is mass, $L$ is length, and $T$ is time. This unit is the standard SI unit in this category."

dcterms:description

Watt per steradian per square metre

is the SI unit of radiance (

W \cdot s r^{- 1} \cdot m^{- 2}

), while that of spectral radiance in frequency is the watt per steradian per square metre per hertz (

W \cdot s r^{- 1} \cdot m^{- 2} \cdot H z^{- 1}

) and that of spectral radiance in wavelength is the watt per steradian per square metre, per metre (

W \cdot s r^{- 1} \cdot m^{- 3}

), commonly the watt per steradian per square metre per nanometre (

W \cdot s r^{- 1} \cdot m^{- 2} \cdot n m^{- 1}

). It has a dimension of

M L^{- 4} T^{- 3}

where

M

is mass,

L

is length, and

T

is time. This unit is the standard SI unit in this category."
