Handy Units
kPa to mmHgkPa → mmHg
1 kPa = 7.50062 mmHg · 1 mmHg = 0.133322 kPa
Formula
mmHg ≈ kPa × 7.50062
Example: 240 kPa = 240 × 7.50062 = 1,800.15 mmHg
These units differ only by a fixed factor: multiply by it to convert, divide to go back. The factors are exact international definitions (for example 1 inch = 2.54 cm exactly); results are rounded only for display.
