Question

How can I convert grams (g) for force in the operating characteristic to Newtons (N)?

Answer

Use the following formula to convert kgf (kilogram-force) to N (Newtons):

1 kgf = 9.80665 N

Therefore, 1 N is equivalent to approximately 102 g.
1 gf to 1/102 N

Example: 140 gf to 1.37 N

The unit for force in the operating characteristics for switches was previously expressed mainly in gram-force (g-f). Presently, however, the unit Newtons (N) is used under the new Japanese Measurement Law that went into force in 1992.
