Express the pressure numerically in atmospheres.

Question

the pressure in car tires is often measured in pounds per square inch (lb/in^2), with the recommended pressure being in the range of 25 to 45 lb/in.2. Suppose a tire has a pressure of 44.0 lb/in.^2 . Convert 44.0 lb/in.^2 to its equivalent in atmospheres.

Answer 1

1 atm = 14.7 lb/in²

Therefore,

(1 atm/ 14.7 lb/in²) (44.0 lb/in²) = 2.993 = 2.99 atm
