When doing push-ups what is the equivalent weight when bench pressing?

When I do push ups what is the equivalent to when I do bench pressing. I’m 180 lbs. Would that mean I lift my full weight or my upper body?

depends on how much weight is going through your feet—stick a bathroom scale under your feet and subtract that from 180 to get how much weight is going through your hands (or you could use 2 scales–one under each hand, to get it directly)
