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 millibar
To convert kilopascals to millibar, multiply the value by 10. Pressure conversions link structural loading, material strength grades and mechanical system ratings across metric and US practice.
Millibar (mbar)
The millibar (mbar) is one thousandth of a bar.
- Origin
- A meteorological subdivision of the bar, equal to the hectopascal.
- Where it is used
- Used for atmospheric pressure, ventilation and low pressure differentials.
- Relation to SI
- 1 mbar = 100 Pa = 1 hPa.
Frequently asked questions
How many millibar are in one kilopascal?
1 kPa equals 10 mbar.
How do I convert kilopascals to millibar?
Multiply the value by 10. For example, 10 kPa equals 100 mbar.
How do I convert back from millibar to kilopascals?
1 mbar equals 0.1 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.
