Worked Examples
Example 1: Convert Height
Problem:Convert 6 feet 2 inches to centimeters.
Solution:Total inches = 6 × 12 + 2 = 74 inches\n\nCentimeters = 74 × 2.54 = 187.96 cm\n\nRounded: 188 cm = 1.88 m
Result:188 cm (1.88 m)
Example 2: Predict Child Height
Problem:Mother: 165 cm, Father: 180 cm. Predict son's height.
Solution:Boy formula:\n(Mother + Father + 13) / 2\n= (165 + 180 + 13) / 2\n= 358 / 2 = 179 cm\n\nRange: 170.5 - 187.5 cm
Result:~179 cm (5'10\") ± 8.5 cm
Example 3: Metric to Imperial
Problem:Height is 162 cm. What is this in feet and inches?
Solution:Feet = 162 ÷ 30.48 = 5.31\n\nWhole feet = 5\nRemaining: 0.31 × 12 = 3.7 inches\n\nAnswer: 5 ft 4 in
Result:5 feet 4 inches
Frequently Asked Questions
How accurate is the height prediction?
Mid-parent formula predicts within ±8.5 cm (3.3 in) for most people. Genetics, nutrition, health, and other factors affect actual height. It's an estimate, not a guarantee.
What is the mid-parent height formula?
For boys: (mother's height + father's height + 13cm) / 2. For girls: (mother's height + father's height - 13cm) / 2. The 13cm adjusts for average male-female height difference.
What factors affect height?
Genetics (60-80%), nutrition, sleep, exercise, hormones, and health conditions. Chronic illness or malnutrition during childhood can reduce adult height.
Is morning height different from evening?
Yes, you're about 1-2 cm taller in the morning. Spinal discs compress during the day from gravity. Medical measurements are often taken in the morning for consistency.
