Enter the initial and final weight into the calculator to determine the weight difference. This calculator can also evaluate any of the variables given the others are known.

## Weight Difference Formula

The following formula is used to calculate the weight difference.

WD = W2 - W1

Variables:

• WD is the weight difference (kg or lbs)
• W1 is the initial weight (kg or lbs)
• W2 is the final weight (kg or lbs)

To calculate the weight difference, subtract the initial weight from the final weight. The result will be the weight difference, which can be positive (if the weight has increased) or negative (if the weight has decreased).

## What is a Weight Difference?

Weight difference refers to the variation in weight between two objects or two measurements of the same object at different times. This could be due to various factors such as changes in mass, gravity, or density. In health and fitness, weight difference often refers to the change in a person’s body weight over a certain period, usually as a result of diet, exercise, or other lifestyle changes.

## How to Calculate Weight Difference?

The following steps outline how to calculate the Weight Difference using the formula WD = W2 – W1.

1. First, determine the initial weight (W1) in kilograms or pounds.
2. Next, determine the final weight (W2) in kilograms or pounds.
3. Next, subtract the initial weight (W1) from the final weight (W2) using the formula WD = W2 – W1.
4. Finally, calculate the Weight Difference (WD) in kilograms or pounds.
5. After inserting the variables and calculating the result, check your answer with a calculator.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Initial weight (W1) = 50 kg

Final weight (W2) = 45 kg
