Live converter
kg/cm2 means kgf/cm2 here (pressure, not mass).
psi = lbf/in2 (pound-force per square inch).
Derived from exact definitions: 1 kgf = 9.80665 N, 1 cm2 = 10^-4 m2, 1 lbf = 4.4482216152605 N, 1 in = 0.0254 m. No rounded lookup tables involved.

Frequently asked questions
What is 1 kg/cm2 in psi?
1 kg/cm2 equals 14.2233 psi. In pressure work, kg/cm2 means kilogram-force per square centimetre (kgf/cm2), and the exact conversion factor is 14.22334330711956 psi per kgf/cm2, derived from 98066.5 Pa / 6894.757293168 Pa.
How do I convert kg/cm2 to psi?
Multiply the kg/cm2 value by 14.223343307. Formula: psi = kgf/cm2 x 14.223343307. Example: 7 kg/cm2 x 14.223343307 = 99.5634 psi. The factor comes from exact definitions: 1 kgf/cm2 = 98066.5 Pa and 1 psi = 6894.757293168 Pa.
How do I convert psi to kg/cm2?
Divide the psi value by 14.223343307, or equivalently multiply by 0.07030696. Formula: kgf/cm2 = psi / 14.223343307. Example: 32 psi / 14.223343307 = 2.2498 kgf/cm2. Round-trip conversion is exact to the displayed precision.
What is 2.2 kg/cm2 in psi?
2.2 kg/cm2 equals 31.2914 psi (about 31.29 psi). This is the textbook example because a typical car tire pressure of 2.2 kgf/cm2 corresponds to roughly 31 to 32 psi. Always confirm against the placard on your own vehicle.
What is 10 kg/cm2 in psi?
10 kg/cm2 equals 142.2334 psi. Calculation: 10 x 14.223343307 = 142.23343307, which rounds to 142.2334 psi at 4 decimal places. At this range you are typically dealing with hydraulics or industrial pressure gauges.
What is 7 kg/cm2 in psi?
7 kg/cm2 equals 99.5634 psi. Calculation: 7 x 14.223343307 = 99.56340315, which rounds to 99.5634 psi. Truck tires commonly run near this range, around 100 psi.
What is 3.6 kg/cm2 in psi?
3.6 kg/cm2 equals 51.204 psi. Calculation: 3.6 x 14.223343307 = 51.2040359, which rounds to 51.204 psi. This is a common range for light truck and van tires.
How many kg/cm2 are in 1 psi?
1 psi equals 0.07030696 kgf/cm2. This is the exact inverse of the forward factor: 1 / 14.22334330711956 = 0.0703069579639 kgf/cm2 per psi. Use it to convert psi back to kg/cm2 by multiplication.
What is 9 psi in kg/cm2?
9 psi equals 0.632763 kgf/cm2. Calculation: 9 x 0.0703069579639 = 0.63276262, which rounds to 0.632763 kgf/cm2 at 6 decimal places.
What is 32 psi in kg/cm2?
32 psi equals 2.2498 kgf/cm2. Calculation: 32 x 0.0703069579639 = 2.24982265, which rounds to 2.2498 kgf/cm2. Many passenger cars specify tire pressures between 30 and 35 psi, i.e. roughly 2.1 to 2.4 kgf/cm2.
What is 150 psi in kg/cm2?
150 psi equals 10.5460 kgf/cm2. Calculation: 150 x 0.0703069579639 = 10.54604369, which rounds to 10.5460 kgf/cm2. This is a typical range for bicycle shock pumps and some hydraulic accumulators.
Is kg/cm2 the same as kgf/cm2?
In pressure contexts, yes: kg/cm2 is shorthand for kgf/cm2, kilogram-force per square centimetre. Strictly, kg is a unit of mass while kgf is a unit of force (1 kgf = 9.80665 N), and pressure is force per area. So 1 kgf/cm2 = 98.0665 kPa exactly, which is the value this converter uses.
How many psi is 1 bar compared to 1 kg/cm2?
1 bar equals 14.5038 psi, while 1 kgf/cm2 equals 14.2233 psi. So 1 kgf/cm2 = 0.980665 bar; the two units are close but not identical. Gauges marked bar and gauges marked kg/cm2 differ by about 2 percent, which matters when setting tire or hydraulic pressures.
Do I need to add atmospheric pressure when converting kg/cm2 to psi?
No. Unit conversion never adds atmospheric pressure; 2.2 kgf/cm2 converts to 31.2914 psi as-is. Whether to add 14.7 psi depends on gauge versus absolute reference (psig vs psia), not on the unit conversion itself. Most tire and workshop gauges read gauge pressure, so compare like with like.
Method and derivation
This tool converts by the exact SI chain, not by a rounded table lookup:
1 kgf = 9.80665 N (exact, standard gravity)
1 cm2 = 10^-4 m2 (exact)
1 lbf = 4.4482216152605 N (exact)
1 in = 0.0254 m (exact)
1 kgf/cm2 = 9.80665 N / 10^-4 m2 = 98066.5 Pa (exact)
1 psi = 4.4482216152605 N / 0.0254^2 m2 = 6894.757293168 Pa
factor = 98066.5 / 6894.757293168 = 14.22334330711956 psi per kgf/cm2
inverse = 1 / 14.22334330711956 = 0.0703069579639 kgf/cm2 per psiRelated pressure units (per 1 kgf/cm2)
