Pressure is the perpendicular force applied per unit area of a surface. It has SI unit Pascal (Pressure is said to be 1 Pascal if a force of 1 Newton is applied on an area of 1m2). The formula for pressure is given as the force per unit area. It can be represented as a formula in the form of, P = F / A. Where P is pressure, F is the force acting perpendicular to the surface and A is the surface area on which force is applied. Let’s learn about the conversion of one form of pressure into another,
We can use the following conversion factor to get from pounds per square inch (psi) to kilograms per square centimeter (kg/cm²):
0.070307 kg/cm2 = 1 psi
Therefore, increase the psi value by 0.070307 to convert it to kg/cm².
As an illustration, if your pressure is 100 psi:
0.070307 kg/cm^ * 100 psi/psi ≈ 7.03 kg/cm²
Thus, 7.03 kg/cm² is roughly equivalent to 100 psi.
PSI to kg/cm2 Conversion
PSI is one of the various units used to describe pressure. PSI stands for Pound per Square Inch (Pressure is said to be 1 PSI when 1 pound-force acts on an area of 1 square inch). Tyre pressure is generally measured in PSI.
PSI = pound force / area in inch square
1 PSI = 0.070307 kilogram force per centimeter square
To convert PSI value to kg/cm2 multiply it by 0.070307.
Derivation
1 pound = 0.45359237 kg
1 in2 = 6.4516 cm2 .
Now, 1 PSI = 1 lbf / 1 in2
= (0.45359237 / 6.4516) kg/cm2
1 PSI = 0.070307 kg/cm2
To convert kg/cm2 to PSI Value multiply it by 14.2233
1 PSI = 6,894.76 pascals (Pa)
1 kg/cm² = 98066.5 pascals (Pa)
PSI value x 6,894.76 Pa = kg/cm2 value x 98066.5 Pa
PSI value = kg/cm2 value x 14.2233
Sample Problems
Question 1: Convert 2.5 PSI to kg/cm2.
Solution:
2.5 PSI = 2.5 × 0.070307 kg/cm2
= 0.1757675 kg/cm2
Question 2: Is 20 PSI same as 15 kg/cm2.
Solution:
20 PSI = 20 × 0.070307 kg/cm2
= 1.40614 kg/cm2
Which is not equal to 15 kg/cm2. So 20 PSI is not same as 15 kg/cm2.
Question 3: If a 4 lb force is acting on a surface of area 2 in2. Find the pressure in kg/cm2.
Solution:
Pressure in PSI = 4/2 PSI
= 2 PSI
(Converting 2 PSI to kg/cm2 )
= 2 × 0.070307 kg/cm2
= 0.140674 kg/cm2 .
Question 4: Force of 2-kilo pounds acts on a surface of area 10 in2. Find the pressure in kg/cm2.
Solution:
Pressure in PSI = 1000/10 PSI
= 100 PSI
(Converting 100 PSI to kg/cm2 )
= 100 × 0.070307 kg/cm2
= 7.0307 kg/cm2 .
Question 5: Convert 1.5 PSI to kg/cm2.
Solution:
1.5 PSI = 1.5 × 0.070307 kg/cm2
= 0.1054605 kg/cm2
Question 6: Write 125 PSI in kg/cm2.
Solution:
125 PSI = 125 × 0.070307 kg/cm2
= 0.8.788375 kg/cm2
