You might know the Einstein's equation
e= mc^2
where e is energy, m is mass and c is the speed of light in a vaccum.
Find out how many joules of work is done by the fire(I think there may be equipment to do this)
Now substitute in SI units to the equation and get the mass of fire as,
m = e / c^2
multiply by g for the weight, i.e,
W = ge/ c^2
where W is the weight in Newtons.
As you can note the mass will be so minuscule it can be considered negligible for real world scenarios.
Hope this helps!

energy isn't created or destroyed the weight of the fire must be the difference between the weight of the fuels and the weight of the by-products.
hard to measure!!

No i don't think so because the flam of the fire burn the oxygen it weight is like a gas.

No, fire is not matter; it's energy. Energy has no mass.

i think no fire has no mass like they say it's energy in it's purest form BUT if there is something combined with fire it will have mass........... but i'm still doubting if fire has no mass fire can float........

no it doesn't! its pure energy
