Convert Kilopascals to Bar
Kilopascals to bar is the conversion you need when a pressure is given in kPa but the gauge, spec, or industry you're working in prefers bar. One kilopascal is exactly 0.01 bar, so the number gets much smaller when you switch from kilopascals to bar.

The formula
To convert kilopascals to bar, multiply the number of kilopascals by 0.01:
bar = kilopascals × 0.01
A worked example
Say you have a reading of 100 kPa and want it in bar:
100 × 0.01 = 1 bar
So 100 kilopascals is exactly 1 bar.
Why the number is exact
Both units are pinned to the pascal by definition: a kilopascal is exactly 1000 pascals, and a bar is exactly 100,000 pascals. Divide one by the other and a kilopascal comes out as exactly 0.01 bar — a clean, exact factor with nothing rounded away. That's why 100 kPa lands on exactly 1 bar.
When you'll use it
Reading pressure specs in fields that favor bar — like diving, weather, or European industrial equipment — when your source value is in kilopascals, or matching a kPa gauge to a bar-labeled system.
Frequently asked questions
How many bar are in a kilopascal?
Exactly 0.01 bar. The bar is defined as exactly 100,000 pascals and a kilopascal is exactly 1000 pascals, so a kilopascal is one hundredth of a bar.
How many kilopascals are in a bar?
Exactly 100 kilopascals. A bar is 100,000 pascals and a kilopascal is 1000 pascals, so it takes 100 kilopascals to make one bar.
Is the kilopascals to bar conversion exact?
Yes. Both units are defined directly from the pascal, so a kilopascal is exactly 0.01 bar — nothing is rounded.
