Kilopascal (kPa)
The kilopascal (kPa) equals 1,000 pascals.
- Origin
- A decimal multiple of the SI pascal.
- Where it is used
- Used for imposed floor loads, soil bearing pressure and wind loading in codes.
- Relation to SI
- 1 kPa = 1,000 Pa = 1 kN/m².

Converting kilopascals to bar
To convert kilopascals to bar, multiply the value by 0.01. Pressure conversions link structural loading, material strength grades and mechanical system ratings across metric and US practice.
Bar (bar)
The bar is a metric pressure unit close to atmospheric pressure at sea level.
- Origin
- A non-SI unit retained in industry, defined as exactly 100,000 Pa.
- Where it is used
- Used for pipework, pumps, hydraulics and pressure testing.
- Relation to SI
- 1 bar = 100,000 Pa = 100 kPa exactly.
Frequently asked questions
How many bar are in one kilopascal?
1 kPa equals 0.01 bar.
How do I convert kilopascals to bar?
Multiply the value by 0.01. For example, 10 kPa equals 0.1 bar.
How do I convert back from bar to kilopascals?
1 bar equals 100 kPa. The converter above works in both directions, so you can type into either field.
How does pressure relate to structural loading?
One kilopascal equals one kilonewton per square meter, which is why imposed floor loads and wind pressures are stated in kPa or kN/m².
Why are concrete and steel grades given in MPa?
One megapascal equals one newton per square millimeter, which matches the millimeter cross-sections used in structural design, so C30/37 or S355 read directly as stress limits.
