Conversion Formula
The formula to convert psi to pa involves multiplying the psi value by 6894.76 because 1 psi equals 6894.76 pa. This works because the pascal is the SI unit of pressure, defined as one newton per square meter, while psi measures pounds-force per square inch. Therefore, multiplying ensures the units align.
- Start with the psi value, for example, 0.5 psi.
- Multiply 0.5 by 6894.76 (the conversion factor).
- 0.5 * 6894.76 = 3447.38 pa.
- This gives the pressure in pascals.
Conversion Example
- Convert 2 psi to pa:
- Multiply 2 by 6894.76.
- 2 * 6894.76 = 13789.52 pa.
- Convert 1 psi to pa:
- Multiply 1 by 6894.76.
- 1 * 6894.76 = 6894.76 pa.
- Convert 5 psi to pa:
- Multiply 5 by 6894.76.
- 5 * 6894.76 = 34473.80 pa.
- Convert 0.1 psi to pa:
- Multiply 0.1 by 6894.76.
- 0.1 * 6894.76 = 689.476 pa.
