How to use it

  1. Type the value in the kilopascals box.
  2. Read the result in bar as you type, and pick the precision you need.
  3. Swap the direction to convert back, or copy the result.

How it is calculated

bar = kPa × 0.01

Multiply the value in kilopascals by 0.01 to get bar.

Example

To convert 25 kPa to bar: 25 × 0.01 = 0.25 bar.

About the units

Kilopascal
Exactly 1000 pascals, widely used for tyre pressure and engineering systems.
Bar
A metric unit equal to exactly 100,000 pascals, close to atmospheric pressure at sea level.

Limits and caveats

  • Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
  • Both unit factors are exact by their official definitions.

Questions about this tool

How many bar are in one kilopascal?

1 kPa = 0.01 bar exactly.

How do I convert kilopascals to bar?

Use bar = kPa × 0.01. For example, 25 kPa = 0.25 bar.

How many kilopascals are in one bar?

1 bar = 100 kPa.

What is the difference between gauge and absolute pressure?

Gauge pressure is measured from the surrounding air pressure, while absolute pressure starts from a perfect vacuum. These converters change the unit only, so a gauge reading stays a gauge reading.

Are torr and mmHg the same?

Almost. One torr is 101325/760 Pa, about 133.322368 Pa, and one conventional mmHg is 133.322387 Pa, a difference of less than one part per million. For everyday use you can treat them as equal.
