In the weight formula F = mg, which value is used for g?

The main idea is that weight comes from multiplying mass by the acceleration due to gravity, g. On Earth, g is about 9.8 m/s^2, but for simple calculations in many school problems it’s common to round to 10 m/s^2 so numbers stay neat and easy to work with. That’s why 10 m/s^2 is used here. Using 9.8 or 9.81 would be more precise and would give slightly different weights, while 11 m/s^2 would imply a stronger pull than actually exists on Earth. So 10 m/s^2 is the practical choice in this context.
