Hi all,

Regarding API 617 Force and Moment equations in SI Units, are they included 1.85 times of NEMA?

Can we derived NEMA in SI unit from API 617 by deviding right side by 1.85?

For example, equation (2.E-1a) API617 is Fr + 1.09Mr <= 54.1De --> NEMA in SI Unit is Fr + 1.09Mr <= 29.24De

Since this is true for US units in API617.
