Chemistry Conversion Problem help please...:)?

Question

28.75lb y^(-2) in ^(-1) to atm ( y=year,lb=pound)

oh and can someone please tell me what does weight have to do with years and pressure(atm's)

Answer 1

Please provide all info (what are you measuring?)
This can't be a value/unit for pressure

Pressure and weight are related through the equation
pressure= weight / the surface on which the force due to the weight is applied. So you could have lb.in(^-2) as unit. The latter unit is be called psi and 1 atm = 14.6956 psi

years have nothing to do with pressure. There is something very wrong here, maybe the way you did the calculations for reaching this type of unit.
