About Millimeter of Mercury and Kilopascal

Detailed information about both units of measurement.

SCIENTIFIC UNIT

Millimeter of Mercury

mmHg
Definition
A pressure unit used in medicine for blood pressure measurement and in barometric readings.
SI / Standard Information
1 mmHg ≈ 133.322 Pa. Nearly identical to 1 Torr. Used for blood pressure (120/80 mmHg) and some barometric measurements.
Approximate Comparison
One mmHg is the pressure exerted by a 1 mm column of mercury at standard gravity.
Practical Applications
  • Blood pressure measurement in medicine
  • Central venous pressure monitoring
  • Ophthalmology (intraocular pressure)
  • Some barometric pressure readings
Real-World Examples
  • Normal blood pressure is 120/80 mmHg
  • Eye pressure is normally 10-21 mmHg
  • A standard mercury barometer reads 760 mmHg
METRIC UNIT

Kilopascal

kPa
Definition
One thousand pascals. Commonly used for tire pressure, weather, and engineering specifications.
SI / Standard Information
SI-derived unit (kPa). 1 kPa = 1,000 Pa. The most practical metric unit for everyday pressure measurements globally.
Approximate Comparison
One kilopascal is about 0.145 PSI or roughly the pressure exerted by a 10 cm column of water.
Practical Applications
  • Tire pressure worldwide (except US)
  • Weather and atmospheric pressure
  • HVAC system static pressure
  • Hydraulic system pressure
Real-World Examples
  • Car tire pressure is typically 200-250 kPa
  • Standard atmospheric pressure is 101.325 kPa
  • A bicycle tire is about 300-450 kPa
