Understanding BMI (Body Mass Index)
BMI is one of the most commonly used health indicators worldwide. It estimates body fat based on height and weight.
BMI Formula
BMI=Height (m)2Weight (kg)
Where:
- Weight is measured in kilograms
- Height is measured in meters
BMI Categories
The calculator classifies BMI into four categories.
| BMI Range | Weight Status |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal Weight |
| 25 – 29.9 | Overweight |
| 30 and above | Obese |
What Is Ideal Weight Range?
Ideal weight refers to a healthy weight range based on your height.
The calculator estimates this range using healthy BMI values between 18.5 and 24.9.
Ideal Weight Formula
Minimum Healthy Weight:
Minimum Weight=18.5×Height(m)2
Maximum Healthy Weight:
Maximum Weight=24.9×Height(m)2
Daily Calorie Requirement Calculation
The calculator also estimates how many calories your body needs daily for basic functioning.
This is based on the Basal Metabolic Rate (BMR) formula.
Formula for Men
Calories=(10×Weight)+(6.25×Height)−(5×Age)+5
Formula for Women
Calories=(10×Weight)+(6.25×Height)−(5×Age)−161
These formulas estimate the number of calories your body burns daily at rest.
Example Calculation
Let’s understand the calculator with a practical example.
Example Data
| Input | Value |
|---|---|
| Age | 28 years |
| Height | 175 cm |
| Weight | 72 kg |
| Gender | Male |
Step 1: Convert Height to Meters
175 cm = 1.75 meters
Step 2: Calculate BMI
BMI = 72 ÷ (1.75 × 1.75)
BMI = 23.5
Result:
Normal Weight
Step 3: Calculate Ideal Weight Range
Minimum:
18.5 × (1.75 × 1.75) = 56.7 kg
Maximum:
24.9 × (1.75 × 1.75) = 76.2 kg
Ideal Weight Range:
56.7 kg – 76.2 kg
Step 4: Calculate Daily Calories
Calories = (10 × 72) + (6.25 × 175) − (5 × 28) + 5
Calories = 1679 kcal/day
