Healthy Weight Range Calculator
The Healthy Weight Range Calculator computes healthy weight range from the relation weight = BMI x height in metres squared, healthy BMI from 18.5 to 24.9. It takes 3 inputs (height in m, lower healthy bmi, upper healthy bmi) and returns the healthy weight range. Because this is a pure mathematical or physical formula rather than a jurisdiction-specific rule, the result never changes over time: the same inputs always produce the same answer, so you can rely on it whether you are checking homework, sizing a design, or sanity-checking another tool. Enter your values in the fields below and the result updates instantly; you can also share a permalink that pre-fills the exact calculation, which is useful for teaching, reports, or collaboration. For example, with height = 1.6 m, lower healthy bmi = 18.5, upper healthy bmi = 24.9, the healthy weight range works out to 47.36, and the worked example further down the page shows every step so you can follow the arithmetic and reproduce it by hand. The method is the standard form documented by CDC About Adult BMI, and the figure above each result carries the date it was last verified. This tool is general information and is not a substitute for professional engineering, medical, financial, or scientific advice; always check critical results against the primary source and your own judgement.
With Height = 1.6 m, Lower healthy BMI = 18.5, Upper healthy BMI = 24.9, the result is 47.36.

The formula
weight = BMI x height in metres squared, healthy BMI from 18.5 to 24.9
Worked example
With Height = 1.6 m, Lower healthy BMI = 18.5, Upper healthy BMI = 24.9:
- Square the height: 1.6 x 1.6 = 2.5600000000000005
- Lower weight = 18.5 x 2.5600000000000005 = 47.36000000000001
- Upper weight = 24.9 x 2.5600000000000005 = 63.74400000000001
- Healthy Weight Range = 47.36
This worked example is one of the automated golden-value tests this calculator must pass before it can publish.
What this assumes
- Inputs are real numbers in the units shown.
- The result is the exact value of weight = BMI x height in metres squared, healthy BMI from 18.5 to 24.9; general information, not professional advice.
Frequently asked questions
What formula does this use?
weight = BMI x height in metres squared, healthy BMI from 18.5 to 24.9, the standard form documented by CDC About Adult BMI.
Does the result ever change over time?
No. This is a pure formula with no external rate, so the same inputs always give the same result.
