What is a Kilopascal?
The kilopascal (kPa) is a derived SI unit of pressure, equal to 1,000 Pascals. It is widely used in engineering, meteorology, and science globally.
What is a Torr?
A Torr is a non-SI unit of pressure based on an absolute scale, defined as exactly 1/760 of a standard atmosphere. It is heavily used in vacuum physics.
Torr vs. mmHg
While technically distinct by a fraction of a percent, 1 Torr and 1 mmHg are considered functionally identical in almost all practical and laboratory applications.
Standard Atmospheric Pressure
At sea level, standard atmospheric pressure is defined as 101.325 kPa, which perfectly equals 760 Torr, 760 mmHg, or 1 atm.
Common Pressure Conversions
Frequently used pressure benchmarks converted across standard scientific and engineering units.
| Pressure Scenario | Kilopascals (kPa) | Torr / mmHg | Atmospheres (atm) |
|---|---|---|---|
| Standard Atmosphere | 101.325 kPa | 760 Torr | 1 atm |
| Typical Car Tyre | ~220 kPa | ~1,650 Torr | ~2.17 atm |
| Rough Vacuum | 10 kPa | 75.006 Torr | 0.098 atm |
| High Vacuum | 0.001 kPa (1 Pa) | 0.0075 Torr | 0.0000098 atm |
| 10m Underwater | ~199.3 kPa (Absolute) | ~1,495 Torr | ~1.96 atm |
Pressure Converter FAQ
Answers to the most frequently asked questions about converting kilopascals to Torr and other pressure units.
To convert kPa to Torr, multiply the pressure value in kilopascals by 7.50061683. For example, 100 kPa is equal to 750.062 Torr. Our calculator handles this multiplication instantly with high precision.
For almost all practical, medical, and scientific purposes, 1 Torr is considered exactly equal to 1 mmHg. The technical difference is less than 0.000015%, so they are used interchangeably in most fields.
The kilopascal (kPa) is a standard SI unit of pressure. It is commonly used in scientific research, engineering, meteorology (weather reporting), and in many countries outside the US, for measuring vehicle tyre pressure.
Standard atmospheric pressure (1 atm) at sea level is defined as exactly 101.325 kPa, which is equivalent to exactly 760 Torr (or 760 mmHg).
Yes. You can enter negative values to represent gauge pressure (pressure relative to ambient atmospheric pressure) or vacuum readings. The mathematical conversion ratio remains exactly the same.
