How to Convert Kilopascal to Torr

To convert Kilopascal to Torr, multiply kPa by 7.50062 because 1 kPa ≈ 7.50062 Torr.

Conversion Formula:

value * 7.50062

Understanding the Conversion

Kilopascal to Torr is useful when SI readings must be expressed on the Torr scale for vacuum systems, semiconductor tools, or lab instrumentation. Since 1 kPa ≈ 7.50062 Torr, multiplying kPa by 7.50062 converts to Torr. This bridges atmospheric-style units to vacuum-centric units.

Reference points: 101.325 kPa ≈ 760 Torr (1 atm), 10 kPa ≈ 75 Torr (rough vacuum), and 0.133 kPa ≈ 1 Torr (low absolute pressure). Converting to Torr helps align with gauge markings and process recipes that specify Torr thresholds.

The conversion is linear and reversible—divide Torr by 7.50062 to return to kPa.

Conversion Examples

Example: Convert 10 kPa to Torr

Step 1: 10 × 7.50062 = 75.0062.
Step 2: Result ≈ 75 Torr.
Step 3: Rough vacuum level.

10 kPa ≈ 75 Torr

Common rough vacuum reference.

Example: Convert 101.325 kPa to Torr

Step 1: 101.325 × 7.50062 ≈ 760.
Step 2: Result ≈ 760 Torr.
Step 3: Standard atmosphere.

101.325 kPa ≈ 760 Torr

Atmospheric pressure equivalence.

Example: Convert 0.5 kPa to Torr

Step 1: 0.5 × 7.50062 ≈ 3.75.
Step 2: Result ≈ 3.75 Torr.
Step 3: Shows low absolute pressure.

0.5 kPa ≈ 3.75 Torr

Low-pressure scenario for vacuum work.

Conversion Formula

Torr is linked to atmosphere; 760 Torr equals 101.325 kPa. Multiplying kPa by 7.50062 converts to the Torr scale.

Unit Definitions

Kilopascal (kPa)

Metric pressure unit.

1 kPa ≈ 7.50062 Torr; 1 atm = 101.325 kPa = 760 Torr.

Torr (Torr)

Vacuum-related unit defined as 1/760 of standard atmosphere.

Torr to kPa divide by 7.50062; Torr to Pa multiply by 133.322.

Common Use Cases

Vacuum systems: present kPa readings in Torr for operators.
Semiconductor processes: align chamber pressures to Torr specs.
Labs: report low pressures in Torr for consistency with instruments.
Leak testing: compare thresholds expressed in Torr.
Education: illustrate kPa-to-Torr scaling against 1 atm reference.

Frequently Asked Questions

Why 7.50062?

It derives from 760 Torr per 101.325 kPa (1 atmosphere).

Is Torr the same as mmHg?

They are very close; Torr is the defined unit for consistency, while mmHg can vary with temperature/gravity.

How to go back to kPa?

Divide Torr by 7.50062 to return to kPa.
