About Converting Femtonewtons to Yoctonewtons
Femtonewton and Yoctonewton both measure force, and the conversion matters whenever an SI-trained engineer needs to compare notes with a US-trained one, or vice versa. Specifically: Femtonewton is 1e-15 newton units, and yoctonewton is 1e-24 newton units.
Formula
yoctonewtons = femtonewtons × 1000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 femtonewton equals 1e-15 base units, and 1 yoctonewton equals 1e-24 base units, so dividing one by the other gives the direct femtonewton-to-yoctonewton factor of 1000000000.
Simple example
1 fN × 1000000000 = 1,000,000,000 yN
1 femtonewton = 1,000,000,000 yoctonewtons.
Real-world example
10 fN × 1000000000 = 10,000,000,000 yN
10 femtonewtons = 10,000,000,000 yoctonewtons.

Reverse conversion: Yoctonewton to Femtonewton
1 yN × 1e-9 = 1e-9 fN
1 yoctonewton = 1e-9 femtonewtons.
femtonewtons = yoctonewtons × 1e-9
