Specific quantity in the context of "Quotient"

Energy flux is the rate of transfer of energy through a surface. The quantity is defined in two different ways, depending on the context:

1. Total rate of energy transfer (not per unit area); SI units: W = J⋅s.
2. Specific rate of energy transfer (total normalized per unit area); SI units: W⋅m = J⋅m⋅s:
   • This is a vector quantity, its components being determined in terms of the normal (perpendicular) direction to the surface of measurement.
   • This is sometimes called energy flux density, to distinguish it from the first definition.
   • Radiative flux, heat flux, and sound energy flux density (also sound intensity) are specific cases of this meaning.

The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material:$${\displaystyle \gamma ={\frac {W}{V}}\ .}$$Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: $${\displaystyle \gamma =\rho \,g.}$$Its unit of measurement in the International System of Units (SI) is the newton per cubic metre (N/m), expressed in terms of base units as kg⋅m⋅s.A commonly used value is the specific weight of water on Earth at 4 °C (39 °F), which is 9.807 kilonewtons per cubic metre or 62.43 pounds-force per cubic foot.

Specific force (SF) is a mass-specific quantity defined as the quotient of force per unit mass.

It is a physical quantity of kind acceleration, with dimension of length per time squared (TL) and SI units of metre per second squared (m·s).
