Which unit is used to measure pressures?

Which unit is used to measure pressures?

• A. MPS
• B. NFPA 211
• C. kPa Kilo Paschal
• D. Megnehelic gauge

Answer: (C)

Pressure is measured in units that express force per area, with the kilopascal (kPa) as a common metric unit for this purpose. Kilopascal indicates how much pressure exists over a given area, which is exactly what’s being measured in many dryer exhaust contexts. The other options aren’t units for pressure: MPS is a speed unit (meters per second); NFPA 211 is a standard, not a unit; and a Megnehelic gauge is a type of instrument used to measure pressure, not a unit itself.
