Understanding the Formula Behind the Calculator
This tool is based on the standard BMI formula used globally in health sciences.
BMI Formula
BMI=Height2Weight
Where:
- Weight is in kilograms (kg)
- Height is in meters (m)
Convert Height to Meters
Height(m)=100Height(cm)
Required Weight Formula
To find the ideal weight for a target BMI:
Weight=BMI×Height2
This formula is the core of the calculator and helps determine how much you should weigh based on your target BMI.
What the Calculator Shows
After entering your details, the calculator provides three important results:
1. Required Weight for Target BMI
This tells you what your weight should be to achieve your desired BMI.
2. Current BMI
Your current BMI based on height and weight.
3. Weight Difference
Shows how much weight you need to gain or lose.
Example Calculation
Let’s understand how the BMI To Weight Calculator works with a real example.
Given:
- Height = 170 cm
- Current Weight = 75 kg
- Target BMI = 22
Step 1: Convert Height
Height = 170 ÷ 100 = 1.7 m
Step 2: Calculate Required Weight
Weight = 22 × (1.7 × 1.7)
Weight = 22 × 2.89
Weight = 63.58 kg
Step 3: Calculate Current BMI
BMI = 75 ÷ 2.89
BMI = 25.95
Step 4: Calculate Difference
Difference = 63.58 - 75
Difference = -11.42 kg
Final Result:
- Required Weight: 63.58 kg
- Current BMI: 25.95
- Weight Difference: -11.42 kg (you need to lose weight)
