I weigh kg and I lost kg...
By what percentage did my weight decrease?
Type of calculation: Calculating percentage change (decrease).
Calculator usage: Before using the calculator, you must calculate the new weight (80 kg - 8 kg = 72 kg). Then use the Percentage Change CALCULATOR ("What is the percentage change from the Original value to the New value?"). Enter the original weight as "Original" (80) and the new weight as "New" (72). The calculator will calculate the percentage decrease.
Explanation using a formula:
First, let's calculate the new weight after the weight loss:
New weight = Original weight - Weight lost
New weight = 80 kg - 8 kg = 72 kg
Now, we are looking for the percentage change from 80 kg to 72 kg.
Formula: ((New value - Original value) / Original value) * 100%
Percentage change = ((72 - 80) / 80) * 100% = (-8 / 80) * 100% = -0.1 * 100% = -10% (the minus sign indicates a decrease)
Alternative method (using the "Part-to-Whole Percentage CALCULATOR"): You can also calculate what percentage 8 kg (change) is of 80 kg (original weight). Use the Part-to-Whole Percentage CALCULATOR ("What percentage of Y is Z?"). Enter 80 as Y and 8 as Z. You will get 10%. Since the weight decreased, it is a 10% decrease.
