Convective Heat Current (Newton's Law of Cooling)

dQdt = h·A·dT

What it says

Computes the rate of convective heat transfer across a surface from the heat transfer coefficient, area, and temperature difference.

Symbol	Quantity	Dimension
`dQdt`	Heat transfer rate (W)	`M L^2 T^-3`
`h`	Heat transfer coefficient (W/(m^2·K))	`M T^-3 Θ^-1`
`A`	Surface area (m^2)	`L^2`
`dT`	Temperature difference (K)	`Θ`

Enter what you know. No account needed.

h — Heat transfer coefficient (W/(m^2·K))A — Surface area (m^2)dT — Temperature difference (K)
