By using this tool, you can quickly determine if you are underweight, within a healthy range, or overweight, helping guide diet and exercise decisions.

Formula / Working

The BMI Prime is calculated using the formula: BMI Prime=BMIUpper Normal BMI\text{BMI Prime} = \frac{\text{BMI}}{\text{Upper Normal BMI}}BMI Prime=Upper Normal BMIBMI​

Where: BMI=Weight (kg)Height (m)2\text{BMI} = \frac{\text{Weight (kg)}}{\text{Height (m)}^2}BMI=Height (m)2Weight (kg)​

• Weight (kg): Your body weight in kilograms
• Height (m): Your height in meters
• Upper Normal BMI: Usually 25

A BMI Prime of 1.0 means you are at the upper healthy limit, less than 1.0 indicates underweight, and greater than 1.0 indicates overweight.

Examples

Example 1 – Healthy BMI Prime:

• Weight: 70 kg
• Height: 1.75 m
• BMI = 70 / (1.75²) = 22.86
• BMI Prime = 22.86 / 25 = 0.91
  Result: Within healthy range

Example 2 – Overweight BMI Prime:

• Weight: 85 kg
• Height: 1.70 m
• BMI = 85 / (1.70²) = 29.41
• BMI Prime = 29.41 / 25 = 1.18
  Result: Overweight

Example 3 – Underweight BMI Prime:

• Weight: 50 kg
• Height: 1.75 m
• BMI = 50 / (1.75²) = 16.33
• BMI Prime = 16.33 / 25 = 0.65
