About the Height Converter

Convert your height between feet/inches and centimeters with this focused converter. Enter your height in feet and inches to see the centimeter equivalent, or enter centimeters to get feet and inches. The converter updates both directions as you type.

Height is one of the most commonly converted measurements. Medical records, driver's licenses, dating profiles, athletic statistics, and travel documents all may require height in different unit systems. The US uses feet and inches, while most of the world uses centimeters.

This calculator uses the exact international standard: 1 inch = 2.54 cm. Enter feet and inches separately for maximum convenience, and get results in centimeters, meters, and total inches.

Frequently Asked Questions

• How do I convert 5 feet 10 inches to centimeters?

  First calculate total inches: 5 × 12 + 10 = 70 inches. Then multiply by 2.54: 70 × 2.54 = 177.8 cm. So 5'10" = 177.8 cm or 1.778 meters.

• What is 170 cm in feet and inches?

  Divide 170 by 2.54 to get 66.93 inches. Divide by 12: 66.93 / 12 = 5 feet with 6.93 inches remaining. So 170 cm ≈ 5'7".

• How tall is 6 feet in centimeters?

  6 feet = 72 inches = 72 × 2.54 = 182.88 cm. This is often rounded to 183 cm. In meters, it's approximately 1.83 m.

• Is 180 cm tall?

  180 cm equals about 5'11", which is above average for men in most countries. In the US, the average adult male height is 5'9" (175 cm), so 180 cm is about 2 inches taller than average.

• Why do some countries measure height in centimeters?

  Most countries use the metric system, where centimeters are the standard unit for human height. Metric is simpler because it uses base-10 divisions. The US and UK traditionally use feet and inches for height, though medical contexts globally often use cm.

• How accurate is height measurement?

  Height varies by about 1–2 cm throughout the day due to spinal compression. You are tallest in the morning after sleeping and shortest in the evening. Measurement with shoes adds 1–3 cm depending on footwear.
