How to Convert Units of Force
Conversions are performed by using a conversion factor. By knowing the conversion factor, converting between units can become a simple multiplication problem:
S * C = E
Where S is our starting value, C is our conversion factor, and E is our end converted result.
To simply convert from any unit into newtons, for example, from 20 kilogram-force, just multiply by the conversion value in the right column in the table below.
20 kgf * 9.80665 [ (N) / (kgf) ] = 196.133 N
To convert from N into units in the left column divide by the value in the right column or, multiply by the reciprocal, 1/x.
196.133 N / 9.80665 [ (N) / (kgf) ] = 20 kgf
To convert among any units in the left column, say from A to B, you can multiply by the factor for A to convert A into Newtons then divide by the factor for B to convert out of Newtons. Or, you can find the single factor you need by dividing the A factor by the B factor.
For example, to convert from kilogram-force to ounce-force you would multiply by 9.80665 then divide by 0.2780139. Or, multiply by 9.80665/0.2780139 = 35.2739557. So, to convert directly from kgf to ozf, you multiply by 35.2739557.
