According to Wikipedia, Cavendish was able to measure a force of 1.74E-7 N or “roughly the weight of a large grain of sand[13] of 0.13 mg”
However, with my calculations using m=F/g, where g=9.81m/s/s
Gives m=1.74E-7/9.81 = 1.77E-8 kg = 0.0177 mg
Which is much less than 0.13 mg
Am I missing something?
