joule/square meter to Btu (th)/square foot
Please provide values below to convert joule/square meter [J/m^2] to Btu (th)/square foot, or change ↔.
joule/square meter [J/m^2]
Definition: The amount of radiant energy passing through one square meter of surface area.
Historyandorigin: The joule is the SI unit for energy, and this unit measures energy density on a surface.
CurrentUse: Used in physics, especially in radiation and energy transfer analysis.
funfact: Joules are also used in measuring electrical energy, showing the connection between different energy forms!
Btu (th)/square foot
Definition: The thermochemical Btu used to measure radiant energy per square foot.
Historyandorigin: This variant of Btu is slightly larger than the IT version, used historically in industrial settings.
CurrentUse: Occasionally used in historical energy systems or specific scientific applications.
funfact: Even though less common today, the thermochemical Btu was once the go-to unit for calculating energy in large systems!

How to Convert joule/square meter to Btu (th)/square foot
1 joule/square meter [J/m^2] = 0.000088114 Btu (th)/square foot
1 Btu (th)/square foot = 11348.931795 joule/square meter [J/m^2]
we use cross multiplication method
joule/square meter [J/m^2] → Btu (th)/square foot
1 → 0.000088114
1.5 → ?( suppose x)
=>1.5*0.000088114=1*x
by simplifying
x=0.000132171
