45lbs, 20kg

55lbs, 25kg

yeah, so? If someone says they bench 1 pl8, which is it?

135lbs

45lbs = 20,4117kg
44,0925lbs = 20kg

2 plates, 1 bar,

1pl8 is 132lbs or 60kg

These guys are right:

1pl8 is 2 20 kg plates+a 20 kg bar. 2pl8 is 4 20 kg plates+a 20 kg bar(so 2 plates on each side).

>20kg to lbs is 44.01 lbs
>45lbs to kg is 20.4kg
so 45lbs are heavier than 20kg plates
