Explanation of Formulas

Here’s a breakdown of each formula the calculator uses to determine ideal weight:

1. Robinson Formula (1983)

This formula adjusts for height above 152 cm, offering gender-specific ideal weights.

• For Men:
  Ideal weight (kg) = 52 + 1.9 × (height in cm − 152)
• For Women:
  Ideal weight (kg) = 49 + 1.7 × (height in cm − 152)

2. Miller Formula (1983)

Similar to Robinson, the Miller formula calculates ideal weight with slightly lower increments.

• For Men:
  Ideal weight (kg) = 56.2 + 1.41 × (height in cm − 152)
• For Women:
  Ideal weight (kg) = 53.1 + 1.36 × (height in cm − 152)

3. Devine Formula (1974)

Originally created for medical purposes, the Devine formula is still a common standard in healthcare.

• For Men:
  Ideal weight (kg) = 50 + 2.3 × (height in inches − 60)
• For Women:
  Ideal weight (kg) = 45.5 + 2.3 × (height in inches − 60)

4. Hamwi Formula (1964)

The Hamwi formula is one of the earliest methods to calculate ideal weight and remains widely used.

• For Men:
  Ideal weight (kg) = 48 + 2.7 × (height in cm − 152)
• For Women:
  Ideal weight (kg) = 45.5 + 2.2 × (height in cm − 152)

5. Healthy BMI Range

This formula calculates a healthy weight range based on Body Mass Index (BMI) standards.

• Formula:
  Weight (kg) = BMI × (height in meters)²
  Healthy weight range = 18.5 × (height in meters)² to 24.9 × (height in meters)²

Example of Results

Let’s say you input the following:

• Age: 30
• Gender: Female
• Height: 170 cm

Your results might look like this:

| Formula | Ideal Weight (kg) | |---------------------|-------------------| | Robinson (1983) | 57.8 | | Miller (1983) | 59.2 | | Devine (1974) | 58.0 | | Hamwi (1964) | 56.8 | | Healthy BMI Range | 53.5 - 72.3 |
