Information Of Reverse BMI Calculator
A Reverse BMI Calculator helps users determine their body weight based on a known BMI value and height. Unlike a traditional BMI calculator that finds BMI from height and weight, this tool works in the opposite direction. It is especially useful for people setting fitness targets, medical weight goals, or BMI-based health planning.
This calculator is widely used by adults, fitness professionals, and healthcare providers who want an accurate way to calculate weight from BMI and height without complex manual formulas.
What is Reverse BMI Calculator?
A Reverse BMI Calculator is a health calculation tool that estimates body weight when BMI and height are already known. It answers a common question:
“If my BMI is X and my height is Y, what should my weight be?”
This tool is also known as:
1. BMI reverse calculator
2. BMI calculator reverse
3. Inverse BMI calculator
4. BMI to weight calculator
It supports both metric (kg, cm) and imperial (lb, ft/in) units, making it suitable for global users.
How This Calculator Works
The Reverse BMI Calculator uses a medically accepted mathematical relationship between BMI, height, and weight.
Input Required
a. Height (cm or ft/in)
b. Target BMI value
c. Unit system (metric or imperial)
Output Provided
a. Estimated body weight
b. Weight displayed in kg or lb
c. Useful for goal-setting and health comparison
This approach is commonly used in:
Fitness planning
Weight-loss or weight-gain goals
Clinical nutrition assessments
Formula Of Reverse BMI
Standard BMI Formula
The reverse BMI calculation is derived from the standard BMI formula used by global health organizations.
| Formula | Description |
|---|---|
| BMI = Weight (kg) ÷ Height² (m²) | WHO standard |
Reverse BMI Formula
| Formula | Use |
|---|---|
| Weight (kg) = BMI × Height² (m²) | Metric system |
Imperial Version
| Formula |
|---|
| Weight (lb) = (BMI × Height² (in²)) ÷ 703 |
These formulas are recognized by:
World Health Organization (WHO)
Centers for Disease Control and Prevention (CDC)
Step-by-Step Manual Calculation
Example: Metric System
Given:
- Height = 170 cm (1.7 m)
- Target BMI = 22
Steps:
1. Convert height to meters → 1.7 m
2. Square the height → 1.7 × 1.7 = 2.89
3. Multiply by BMI → 22 × 2.89
Result:
Weight ≈ 63.6 kg
This is the same result produced by an accurate reverse BMI calculator.
Reverse BMI Chart (Metric Example)
| Height (cm) | BMI 20 | BMI 22 | BMI 25 |
|---|---|---|---|
| 160 | 51.2 kg | 56.3 kg | 64.0 kg |
| 170 | 57.8 kg | 63.6 kg | 72.3 kg |
| 180 | 64.8 kg | 71.3 kg | 81.0 kg |
Reverse BMI for Adults
The Reverse BMI Calculator is primarily designed for adults aged 18 and above. BMI interpretation differs for:
1. Children
2. Adolescents
3. Pregnant individuals
For adults, BMI categories remain standardized:
| BMI Range | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal |
| 25 – 29.9 | Overweight |
| 30+ | Obese |
Metric vs Imperial Calculation Comparison
| Feature | Metric | Imperial |
|---|---|---|
| Height Unit | meters (m) | inches (in) |
| Weight Unit | kilograms (kg) | pounds (lb) |
| Formula Constant | None | 703 |
| Accuracy | High | High |
