Kilopascals to Millimeters of mercury (kPa to mmHg)
Convert kilopascals to millimeters of mercury: 1 kPa = 7.50062 mmHg. Exact conversion factor, formula, 22-row table and worked examples, with JSON API and MCP access.
Formula
1 kPa = 7.50062 mmHg
millimeters of mercury = kilopascals × 7.500615758 — reverse: kilopascals = millimeters of mercury × 0.1333223874
The factor is derived from the SI definitions of both units (base unit: Pa) as listed in NIST SP 811; results on this page are shown to 6 significant figures, the API returns up to 12.
Worked examples
- 5 kPa = 37.5031 mmHg
- 12.5 kPa = 93.7577 mmHg
- 100 kPa = 750.062 mmHg
