A metric term for pressure is

A metric term for pressure is

• A. Kilopascal
• B. Bar
• C. Psi
• D. Torr

Answer: (A)

Pressure is measured as force per area, and in the metric system the standard unit is the pascal, which is one newton per square meter. A kilopascal is simply 1,000 pascals and is the common metric unit you'll see on HVAC equipment and manuals, making it the best answer for a metric term for pressure. The other units are not metric SI units: a bar is a widely used metric unit but not SI (1 bar equals 100 kilopascals); psi is pounds per square inch and is imperial; Torr uses millimeters of mercury and is not metric. So the kilopascal aligns with the metric/SI convention used for pressures in many HVAC contexts.
