CONVERSION TABLES
This selection of conversion tables will help when making orders with COHLINE UK Ltd

Pressure and Temperature Conversion Table

Pressure Conversion

1 bar = 10 N/cm = 100kPa = 0,1 MPa
= 14,5 psi

Pressure in bar = psi x 0,06895
Pressure in psi = bar x 14,5

 

Temperature Conversion

Temp in F > C = (temp inF -32) * 5/9
Temp in C > F = (1.8 * temp inC) +32
