Find your ideal body weight with our simple Hamwi Equation Calculator. Fast, clear, and easy to use. Get accurate Hamwi Formula results for men and women.
The Hamwi Equation is a simple way to find ideal body weight. It’s easy to learn. It’s easy to use. That’s why we built our Hamwi Equation calculator, so you can get fast and clear results. Many people want to know their healthy weight range. This method gives you a quick answer without hard math or long steps.
The Hamwi formula came out in 1964. It has stayed popular because the steps are short and clear. It uses height and gender to guess ideal weight.
Here is the formula in plain text.
For men:
IBW = 106 + 6 × (height in inches − 60)
For women:
IBW = 100 + 5 × (height in inches − 60)
If you’re under 5 feet, you subtract instead of add.
For men under 5 ft:
IBW = 106 − 6 × (60 − height in inches)
For women under 5 ft:
IBW = 100 − 5 × (60 − height in inches)
This is the correct Hamwi 1964 formula. Some people call it the Hawi equation, but the real name is Hamwi Equation.
Our Hamwi Equation calculator is simple.
You’ll see your ideal body weight in pounds and kilograms. You’ll also see small frame and large frame options. This helps you find a range that fits your body shape.
You don’t need to know the formula. You don’t need math skills. The tool does all the work in a blink. You’ll get a clean and easy result.
Let’s take a quick example to make things clear.
Say a man is 5 feet 10 inches tall. That’s 70 inches.
Height above 60 inches is 10.
Now use the formula.
IBW = 106 + 6 × 10
IBW = 106 + 60
IBW = 166 pounds
To get the weight in kilograms, you multiply by 0.453592.
166 × 0.453592 = 75.29 kg
That’s the ideal weight by the Hamwi Equation.
The calculator does this math for you, so you don’t need to worry about mistakes.
The Hamwi Equation is one of the simplest ways to find ideal body weight. It’s clear. It’s fast. It’s great for daily use. Our Hamwi Equation calculator makes the process even easier. You’ll get instant and accurate results with no stress. If you want a clean and simple tool that works well, this calculator checks every box.
It’s a formula from 1964 that uses height and gender to find ideal body weight.
You start with a base number. Then you add or subtract weight for each inch above or below 5 feet.
Men: 106 + 6 × (height in inches − 60)
Women: 100 + 5 × (height in inches − 60)
You subtract instead of add.
Men: 106 − 6 × (60 − height)
Women: 100 − 5 × (60 − height)
People often say “Hawi,” but the right name is Hamwi Equation.
