Formula
cm = (feet x 12 + inches) x 2.54 | feet = cm / 30.48 | meters = cm / 100
One inch equals exactly 2.54 centimeters. To convert feet and inches to centimeters, first convert to total inches (feet x 12 + inches), then multiply by 2.54. To reverse, divide centimeters by 2.54 to get inches, then divide by 12 for feet.
Worked Examples
Example 1: Basketball Player Height
Problem:Convert 6 feet 6 inches to centimeters and meters.
Solution:Total inches: 6 x 12 + 6 = 78 inches\nCentimeters: 78 x 2.54 = 198.12 cm\nMeters: 198.12 / 100 = 1.9812 m
Result:6 ft 6 in = 198.12 cm = 1.9812 m
Example 2: Passport Height Entry
Problem:A passport requires height in centimeters. Convert 5 feet 4 inches.
Solution:Total inches: 5 x 12 + 4 = 64 inches\nCentimeters: 64 x 2.54 = 162.56 cm\nRounded: 163 cm (typical for passports)
Result:5 ft 4 in = 162.56 cm
Frequently Asked Questions
How do I convert feet and inches to centimeters?
First convert everything to inches by multiplying feet by 12 and adding any remaining inches. Then multiply the total inches by 2.54 to get centimeters. For example, 5 feet 10 inches = (5 x 12) + 10 = 70 inches, and 70 x 2.54 = 177.8 cm. This conversion factor is exact because one inch is defined as exactly 2.54 centimeters by international agreement since 1959.
What is the average human height in different units?
The global average adult male height is approximately 171 cm (5 ft 7.3 in) and the average female height is about 159 cm (5 ft 2.6 in). These averages vary significantly by country. In the Netherlands, the average male height is about 183 cm (6 ft 0 in), while in Guatemala it is about 163 cm (5 ft 4 in). Height measurements are important in medicine, nutrition, and fitness for calculating BMI and other health metrics.
Why do some countries use feet and inches while others use centimeters?
The United States, Liberia, and Myanmar are the only countries that have not officially adopted the metric system for everyday measurements. Most of the world uses centimeters and meters as part of the International System of Units (SI). The UK uses a mix of both systems, with people often stating their height in feet and inches informally but using centimeters in medical settings. The metric system is preferred in science and international commerce due to its decimal-based simplicity.
