Convert your height between feet/inches and centimeters with this easy tool. Enter your height in feet and inches to see the centimeter equivalent, or enter centimeters to get feet and inches. The converter handles both directions instantly.
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.
By calculating this metric accurately, professionals gain actionable insights that support smarter work habits, more realistic scheduling, and improved work-life balance over time. Understanding this metric in precise terms allows professionals to set achievable targets, measure progress objectively, and continuously refine their approach to time and task management.
Quickly convert between the two most common height formats without mental math. Useful for medical forms, passport applications, athletic profiles, and any situation where you need height in a different unit system. Precise quantification supports meaningful goal-setting and accountability, ensuring that improvement efforts are focused on areas with the greatest potential impact on output.
cm = (feet × 12 + inches) × 2.54 meters = cm / 100 total inches = feet × 12 + inches Reverse: total inches = cm / 2.54; feet = floor(total inches / 12); remaining inches = total inches mod 12
Result: 177.8 cm
Total inches = 5 × 12 + 10 = 70 inches. Centimeters = 70 × 2.54 = 177.8 cm = 1.778 meters. This is a common male height in the United States.
In the United States, Canada (informally), and the United Kingdom, height is typically expressed in feet and inches. Most other countries use centimeters. Medical records worldwide increasingly use centimeters for standardization, even in the US.
Global average adult male height is approximately 171 cm (5'7.5"), while adult female height averages about 159 cm (5'2.5"). The tallest populations are in the Netherlands (average male 183 cm) and the shortest in Southeast Asia and Central America. Height has been increasing globally due to improved nutrition.
Some common height conversions: 5'0" = 152 cm, 5'4" = 163 cm, 5'8" = 173 cm, 6'0" = 183 cm, 6'4" = 193 cm. Each inch adds 2.54 cm, and each foot adds 30.48 cm.
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.
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".
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.
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.
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.
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.
