1 atm = 101.325 kPa
1.76 atm
= (1.76 atm) × (101.325 kPa/atm)
= 178.332 kPa
= 178 kPa (to 3 sig. fig.)
1.76 atm
= (1.76 atm) × (101.325 kPa/atm)
= 178.332 kPa
= 178 kPa (to 3 sig. fig.)

use Unit Cancellation
given 1.76 atm, start there and apply converter(s)
1.76 atm (101.325kPa/1atm) = 178.332 kPa
Now you need to round off for sigfigs (something Google always gets wrong)
1.76 has 3 sigfigs
178.332 becomes
178 kPa

參考: Here's a very short 2 minute video on how to work 'unit cancellation' and conversion problems.

Note: In the problem above, I'll typically have the converter in (parens). Converters = (1)
