Height conversion questions
How do I convert 5'7" to centimeters?
Multiply the feet by 30.48 and the inches by 2.54, then add them: 5 ft 7 in = 5×30.48 + 7×2.54 = 152.4 + 17.78 = 170.18 cm. The converter above does this instantly.
Why is my percentile different from someone else's?
Percentile compares you to the height distribution for a specific age and sex, drawn from standard growth references. As you age (or if you change sex), the comparison group changes, so the percentile moves.
Is BMI accurate for everyone?
BMI is a useful screening number, but it does not separate muscle from fat and can mislabel very athletic people. Use it as a rough guide alongside your doctor's assessment, not as a verdict.
