API 620 SI unit 1

[EngFax]

Hi,

Can I use API 620 in SI units just by converting units? will the equations still valid?

Thanks

The equations in API 620 use consistent units. Yes, SI units are acceptable.

If you have a constant value within the equation based on the english units, that constant value may not hold true if you decide to substitute SI units in that equation, so be careful how this constant value was obtained.
