Final answer:
To convert pressure from pounds per square inch (lb/in.²) to atmospheres (atm), divide the pressure in pounds per square inch by 14.7.
Step-by-step explanation:
To convert pressure from pounds per square inch (lb/in.²) to atmospheres (atm), we need to use the conversion factor between these two units.
1 atm = 14.7 lb/in.².
Therefore, we can calculate the pressure in atmospheres by dividing the pressure in pounds per square inch by 14.7.
For the given pressure of 44.5 lb/in.²:
44.5 lb/in.² ÷ 14.7 lb/in.²/atm = 3.03 atm
