The kilopascal (kPa) equals 1,000 pascals and is the most practical unit for everyday pressure measurements in metric countries. Tire pressure, building specifications, and weather reports in Canada, Australia, and Europe commonly use kilopascals. One kilopascal equals 0.01 bar or approximately 0.145 psi, making it a convenient middle ground between scientific and industrial scales.

The millimeter of mercury (mmHg) is a pressure unit equal to about 133.322 pascals, traditionally used in medicine for measuring blood pressure and in meteorology for barometric readings. A normal adult blood pressure of 120/80 mmHg is universally understood by healthcare professionals, making this unit a fixture in clinical settings. One mmHg equals approximately 0.01934 psi or 0.1333 kPa.
