What is the equation to calculate the temperature

[wishstar]

What is the equation to calculate the temperature at a given distance from a heat source (inside a green house)? Example: I want to calculate the temperature at 2m, 3m, 5m, 7m from the heating object like a heater.

There is no such equation. The relationship depends on many factors besides distance.

That depends very strongly on the assumptions. You will be better off just measuring it.

The basic equations are thermal conduction:

Convection:
