Formula: Torr = Kilopascal × 7.501
Multiply any kilopascal value by 7.501 to get torr.
Reverse: Kilopascal = Torr × 0.1333
Common kilopascal values — factor: 1 kPa = 7.501 Torr

The kilopascal (kPa) equals 1,000 pascals and is the practical everyday pressure unit in metric countries. It is the standard unit for tire pressure, blood pressure, and weather maps in countries using SI.
Blood pressure in many countries is expressed in kPa (normal: ~16/10.7 kPa), though mmHg remains dominant in medicine. Car tire pressure is typically 200–250 kPa. Weather maps use hPa (= mbar) for atmospheric pressure.
Interesting fact: The 'bends' (decompression sickness) in scuba diving occurs when dissolved nitrogen forms bubbles as pressure drops — a drop of just a few kPa too quickly can be fatal.
The torr was named after Evangelista Torricelli, who invented the mercury barometer in 1644. One torr is defined as 1/760 of standard atmospheric pressure (133.322 Pa), and is equal to 1 mmHg at 0°C.
Torr is the standard pressure unit in vacuum science and semiconductor manufacturing. High vacuum systems operate at 10⁻³ to 10⁻⁷ torr. Ultra-high vacuum (used in particle accelerators) reaches below 10⁻¹⁰ torr.
Interesting fact: Torricelli's original barometer experiment used a 1-meter tube of mercury that settled at 760 mm above the reservoir — directly defining the unit that would later bear his name.
Converting kilopascal to torr is a common task in engineering, medicine, meteorology, and science. Different industries and countries use different pressure units — PSI in the US, bar in Europe, mmHg in medicine, and pascals in physics — making accurate conversion essential for cross-disciplinary work.
Quick reference: 5 kPa = 37.5 Torr and 10 kPa = 75.01 Torr. For the reverse: 1 Torr = 0.1333 kPa. The exact factor is 1 kPa = 7.501 Torr.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
