Normal blood pressure is around 120/80 mmHg. Atmospheric pressure at sea level is roughly 760 mmHg. In kilopascals, that gives you: 1 mmHg = 0.133322 kPa, 10 mmHg = 1.33322 kPa, 100 mmHg = 13.3322 kPa.
The millimeter of mercury (mmHg) equals approximately 133.322 Pa — the pressure exerted by a 1 mm column of mercury under standard gravity. It is the conventional unit for blood pressure worldwide, even in countries that have otherwise gone fully metric.
The kilopascal (kPa) equals exactly 1,000 pascals. It is the standard pressure unit in modern meteorology, engineering specs outside the US, and most non-US tire-pressure recommendations.
