Height Conversion Basics

Many countries use different measurement units for height such as feet & inches or centimeters. Knowing how to convert them is helpful for health checkups, sports, travel, and clothing size guidance.

• 1 inch = 2.54 cm
• 1 foot = 30.48 cm = 12 inches
• Example: 5′ 6″ ≈ 168 cm

Child Height Prediction Formula

Our tool uses the scientifically-accepted Mid-Parental Height Formula to estimate how tall a child may become as an adult:

• Boys: (Father + Mother + 13 cm) ÷ 2
• Girls: (Father + Mother – 13 cm) ÷ 2
• Height can vary ±5 cm due to individual growth factors

What Affects Height Growth?

• Genetics -- responsible for ~70% of height
• Nutrition -- calcium & protein are essential
• Sleep -- growth hormones peak at night
• Exercise -- sports help improve bone strength
• Health conditions may affect growth rate

When Growth Usually Stops

Height growth slows during late teenage years once growth plates close:

• Boys: usually until age 18–21
• Girls: usually until age 16–18

Tips to Support Healthy Growth

• Eat a balanced diet with milk, eggs, leafy greens & fruits
• Sleep at least 8–10 hours during growth years
• Play height-friendly sports like basketball or swimming
• Avoid junk food & smoking habits

Quick Tip

Height prediction is only an approximate guide. Real height depends on lifestyle, wellness, hormones, and overall development.
