Handy Units
mmHg to kPammHg → kPa
1 mmHg = 0.133322 kPa · 1 kPa = 7.50062 mmHg
Formula
kPa ≈ mmHg ÷ 7.50062
Example: 120 mmHg = 120 ÷ 7.50062 = 15.9987 kPa
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.
