Bar to Kilopascal Converter
Pressure · unit-converter
Convert Bar to Kilopascal with a fixed input and output unit, step-by-step formula line, and reference tables. All calculations bridge through pascal with fixed definitions (standard atmosphere = 101,325 Pa; torr and mmHg = atm/760; plus industrial/manometer units like kgf/cm², inHg, inH2O, and mmH2O).
About Bar
The bar is 100,000 Pa. It is convenient for industrial and approximate atmospheric pressures (1 bar ≈ 1 atm).
About Kilopascal
The kilopascal (kPa) equals 1,000 Pa. It appears in HVAC, building science, and many technical specifications.
How to convert bar to kilopascal
1 bar equals 100 kilopascal in this tool (via pascal):
1 bar = (100000 Pa ÷ 1000 Pa) kpa = 100 kpa
Each bar carries 100000 Pa and each kilopascal 1000 Pa, so one bar equals 100000 ÷ 1000 kpa.
Let p(bar) be pressure in Bar (bar), and p(kpa) in Kilopascal (kpa). Then:
p(kpa) = p(bar) × (100000 / 1000)
Equivalently, divide by how many bar fit into one kpa (Pa per kpa divided by Pa per bar):
p(kpa) = p(bar) ÷ 0.01
Examples
Example #1: Convert 1 bar to kilopascal
1 bar = 1 bar × (100000/1000) kpa = 100 kpa
1 bar = 1 bar ÷ 0.01 = 100 kpa
1 bar × (100,000/1,000) = 100.000000 kpa
Example #2: Convert 10 bar to kilopascal
10 bar = 10 bar × (100000/1000) kpa = 1000 kpa
10 bar = 10 bar ÷ 0.01 = 1000 kpa
10 bar × (100,000/1,000) = 1,000.000000 kpa
Summary
To convert Bar to Kilopascal, multiply the value in bar by (100000 Pa per bar) / (1000 Pa per kpa). Equivalently: value_kpa = value_bar × (100000 / 1000). Numerically, 1 bar equals 100 kpa.
Relationship context
Both Bar and Kilopascal are converted by fixed multiples of the pascal. Multiplying by (Pa per bar) ÷ (Pa per kpa) gives the same result as passing through pascal, keeping bar, atm, PSI, kPa, hPa, torr, and mmHg consistent on the hub.
