A client has a grip test that is 42 kg-force at a body mass of 70 kg. What is the grip-to-mass ratio to two decimals?
- A1.67 kg-force/kg
- B60.00 kg-force/kg
- C0.60 kg-force/kg
- D0.27 kg-force/kg
Show answer and explanations
Answer
C
Relative grip = grip / body mass = 42 / 70 = 0.60 kg-force per kg.
A
This reverses the ratio (70 / 42 = 1.67).
B
This expresses the ratio as a percentage (60%) while keeping the ratio unit.
D
This divides by body weight in pounds (42 / 154 = 0.27) instead of kilograms.
C
Relative grip = grip / body mass = 42 / 70 = 0.60 kg-force per kg.
