Step 1

We know that 1 foot is approximately 0.3048 meters and 1 inch is approximately 0.0254 meters. So, the height of the tallest man in medical history is $8 \times 0.3048 + 11 \times 0.0254 = 2.72$ meters. Show more…

Key Concepts

Body Mass Index (BMI)

BMI is a numerical measure of a person's body fat based on their weight and height. It is calculated by dividing a person's weight in kilograms by the square of their height in meters. BMI serves as a quick assessment tool to categorize individuals into different weight ranges such as underweight, normal weight, overweight, or obese, and is widely used in public health and medical settings.

Unit Conversion

Unit conversion is essential when measurements are given in different systems, such as converting height from feet and inches to meters or centimeters. Consistent units are required to accurately apply formulas like the BMI calculation. Proper conversion ensures that the derived values are correct and comparable across different datasets and medical records.
