Question
What is the relationship among units of pressure?
Answer
The relationships are given in the following table.
kgf/cm2 | mmHg | mmH2O | Pa | |
1 kgf/cm2 | 1 | 735.559 | 1.000028 x 104 | 0.0980665M |
1 mmHg | 1.3595 x 10-3 | 1 | 1.3595 x 10 | 0.133322k |
1 mmH2O | 0.99997 x 10-4 | 7.356 x 10-2 | 1 | 0.00980665k |
1 Pa(N/m2) | 1.0197 x 10-5 | 7.5006 x 10-3 | 0.10197 | 1 |
Examples:
How many kgf/cm2 is 10 Pa?
Pa = 1.0197 x 10-5 (kgf/cm2), so 10 Pa = 10-4(kgf/cm2).
How many Pa is 10 kgf/cm2?
1 kgf/cm2 = 0.0980665 Mpa, so 10 kgf/cm2 = 0.980665 Mpa.
