1 kgf m equals approximately how many Nm?
A9.8 Nm
B1 Nm
C100 Nm
D0.1 Nm
Answer & Solution
Correct answer: A. 9.8 Nm
1. 1 kgf is the gravitational force on a 1 kg mass at Earth's surface.
2. 1 kgf equals m·g = 1 × 9.8 = 9.8 N.
3. So 1 kgf m equals 9.8 N × 1 m = 9.8 Nm.
4. Hence the conversion factor is 9.8.
