Height Calculation Formula:
| From: | To: |
This calculation determines a person's height based on their body mass index (BMI) and weight. It's derived from the standard BMI formula rearranged to solve for height.
The calculator uses the following formula:
Where:
Explanation: The formula is derived from the standard BMI equation (BMI = weight/height²) by solving for height.
Details: This calculation can be useful when you know a person's weight and BMI but need to estimate their height, such as in certain medical or research contexts.
Tips: Enter weight in kilograms and BMI in kg/m². Both values must be positive numbers.
Q1: How accurate is this height calculation?
A: The calculation is mathematically precise, but its real-world accuracy depends on the accuracy of the input BMI and weight values.
Q2: Can I use pounds instead of kilograms?
A: The formula requires metric units. Convert pounds to kg (1 lb = 0.453592 kg) before using the calculator.
Q3: What if I know the BMI category (normal, overweight, etc.) but not exact BMI?
A: You could use the midpoint of the BMI range for your category, but this will only give an approximate height estimate.
Q4: Why would I need to calculate height this way?
A: This might be useful in research, medical assessments, or when working with historical data where height wasn't recorded.
Q5: Does this work for children?
A: The standard BMI formula is designed for adults. For children, age- and sex-specific BMI charts should be used.
