Kilopascal to Torr: The Essentials
The Kilopascal in Engineering
Kilopascal (kPa) is a unit of pressure measurement. 1 kilopascal is equal to 7.5006168 torr.
What is Torr?
Torr (Torr) is a unit of pressure measurement. 1 torr is equal to 0.1333224 kilopascal.
Pressure Units Across Industries
Pressure measurements vary dramatically by industry. Meteorologists report in millibars or hectopascals, tire shops use PSI, scuba divers think in atmospheres or bar, vacuum engineers work in torr, and hydraulic systems specify in megapascals. A single industrial plant might encounter all these units across different equipment manuals, safety datasheets, and regulatory standards from different countries.

How to Convert Kilopascal to Torr?
We can convert kilopascal to torr by using an example.
Example:
Convert 20 Kilopascal to Torr?
We know 1 Kilopascal = 7.5006168 torr; 1 Torr = 0.1333224 kilopascal.
20 kilopascal = ___Torr
20 × 7.5006168 = 150.01234 Torr (we know 1 kilopascal = 7.5006168 torr)
Answer:
20 kilopascal = 150.01234 torr
How to Convert kPa to Torr (Step-by-Step)
Converting kilopascals to torr is essential for vacuum system specifications and pump performance curves. The conversion factor is 1 kPa = 7.50062 torr.
- Write down the pressure value in kilopascals (kPa).
- Multiply the kPa value by 7.50062.
- The result is the equivalent pressure in torr.
- For rough estimates, multiply by 7.5.

Solved Examples: kPa to Torr
Question 1: A vacuum pump achieves an ultimate pressure of 0.05 kPa. What is this in torr?
Solution:
Pressure in torr = Pressure in kPa × 7.50062
= 0.05 × 7.50062
= 0.375 torr
Answer: 0.05 kPa = 0.375 torr — suitable for freeze-drying applications.
Question 2: A vacuum gauge reads 5 kPa absolute. Convert to torr.
Solution:
Pressure in torr = 5 × 7.50062
= 37.50 torr
Answer: 5 kPa = 37.50 torr — a moderate vacuum used in vacuum packaging.
Question 3: A rotary evaporator operates at 2.67 kPa. Express in torr.
Solution:
Pressure in torr = 2.67 × 7.50062
= 20.03 torr
Answer: 2.67 kPa = 20.0 torr — typical for solvent evaporation at reduced pressure.

Vacuum Pump Specifications: kPa vs Torr
Vacuum pump manufacturers often list ultimate pressure in multiple units. European pumps (Busch, Becker) typically specify in mbar or kPa (absolute), while older US and Asian catalogs use torr or mmHg. A two-stage rotary vane pump might be rated at 0.001 kPa (0.0075 torr), while a dry scroll pump achieves 0.1 kPa (0.75 torr). Knowing the conversion helps compare products across catalogs without confusion.
Vacuum Ranges and Their Applications
Vacuum levels are categorized by pressure: rough vacuum (100-1 kPa / 750-7.5 torr) for vacuum packaging and forming; medium vacuum (1-0.001 kPa / 7.5-0.0075 torr) for freeze-drying, distillation, and coating; high vacuum (<0.001 kPa / <0.0075 torr) for electron microscopy and semiconductor fabrication. Understanding both kPa and torr scales helps specify equipment correctly.
Key Takeaways
- Multiply kPa by 7.50062 to get torr.
- 1 atm = 101.325 kPa = 760 torr (this defines the relationship).
- Quick estimate: multiply kPa by 7.5.
- Vacuum pumps often specify ultimate pressure in both kPa and torr.
- Lower numbers mean better vacuum in both units (measuring absolute pressure).
- The torr is essentially identical to 1 mmHg for practical purposes.
Kilopascal to Torr Conversion Formula
torr = kilopascal × 7.5006168
