The BMI Reverse Calculator allows users to calculate the required weight to achieve a specific BMI based on their height. This tool is useful for individuals aiming to reach a desired body mass index (BMI) target by calculating the corresponding weight.
Historical Background
BMI (Body Mass Index) was introduced by Adolphe Quetelet in the early 19th century as a measure of relative weight based on height. It has since become a widely used tool to categorize individuals based on their weight relative to height, helping to assess whether they are underweight, normal weight, overweight, or obese.
Calculation Formula
The formula used for calculating weight based on a target BMI is:
\[ \text{Weight (kg)} = \text{BMI} \times (\text{Height in meters})^2 \]
Where height is measured in meters and BMI is the desired target.
Example Calculation
If your height is 170 cm and your target BMI is 22:
\[ \text{Height in meters} = \frac{170}{100} = 1.7 \text{ meters} \] \[ \text{Weight (kg)} = 22 \times (1.7)^2 = 22 \times 2.89 = 63.58 \text{ kg} \]
To reach a BMI of 22, you need to weigh approximately 63.58 kg.
