What is the formula for weighted average?

To find a weighted average, multiply each number by its weight, then add the results. If the weights don’t add up to one, find the sum of all the variables multiplied by their weight, then divide by the sum of the weights.

How do you find the weight?

Summary

  1. Weight is a measure of the force of gravity pulling down on an object. It depends on the object’s mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth.
  2. The formula for calculating weight is F = m × 9.8 m/s2, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.
