That is one basic fact of photography. They used to have photography classes in high schools not so long time ago.

But then 1kg of iron does feel much heavier than 1kg of air. And you need to calibrate your scales. Some topics can be debated for ever
Sounds incredible! Don't know about you, but personally I use PEF (Personal Exposure Factor) for each film format. So for 120 it is the exposure meter value, for MF my PEF is 1x for LF it is between 1.0 x to 1.00 x, depending on the precise film format. Works a whole heck, never missed an exposure because of a wrong PEF.
