Convert height from feet and inches into centimeters and meters instantly — useful for medical forms, travel documents, or international size charts.

How It Works

How Height Calculator Works

The calculator converts your feet and inches into total inches (feet × 12 + inches), then multiplies by 2.54 — the exact number of centimeters in one inch — to get the metric equivalent, also shown in meters.

Worked Example

See It In Action

A height of 5 feet 8 inches is 68 total inches, which converts to 172.72 cm, or 1.7272 m.
Real-World Use Cases

Who Uses Height Calculator and Why

  • Converting a height from feet and inches to centimeters for an international visa, immigration, or medical form that requires metric units.
  • Filling out an online profile, dating app, or international clothing size chart that only accepts height in centimeters.
  • Double-checking a doctor's office or school nurse's metric height reading against the imperial figure you're more used to.
  • Converting a child's height measurement for comparison against a metric growth chart used outside the US.
Common Mistakes

Mistakes to Avoid

  • Entering total inches into the "inches" field instead of just the remainder past whole feet (e.g., entering 68 instead of 5 feet + 8 inches) — this double-counts the feet portion and produces a wrong result.
  • Rounding your feet-and-inches measurement before entering it, then expecting a precise centimeter figure — since the conversion itself is exact, any imprecision in the result actually comes from imprecision in the original measurement.
  • Mixing up meters and centimeters when copying the result into a form — a height of 172.72 cm is 1.7272 m, not 17.272 m or 0.17272 m.
Pro Tips

Tips for Best Results

  • If your height was measured to a fraction of an inch, enter that as a decimal (e.g., 8.5 for eight and a half inches) for a more precise centimeter conversion.
  • Keep both the centimeter and meter figures handy — most European medical and official forms specifically expect centimeters, not meters.
Troubleshooting

Fixing Common Problems

The centimeter result looks slightly off from what I expected. — Double check you entered feet and remainder inches separately rather than total inches in one field — that's the most common source of an unexpectedly large or small result.

Glossary

Terms Explained

Metric equivalent: A measurement re-expressed in the metric system (centimeters, meters) from an imperial measurement (feet, inches), here using the exact conversion factor of 2.54 cm per inch.

FAQ

Frequently Asked Questions

Why do international forms ask for height in centimeters?
Most countries outside the U.S. use the metric system for official documents, medical charts, and identification, so centimeters is the standard unit expected on forms like visa applications or international medical records.
How precise is the conversion?
The conversion uses the exact factor of 2.54 cm per inch, so the result is mathematically precise — any rounding you see is just for display purposes.
Can I enter inches as a decimal, like 8.5?
Yes — the inches field accepts decimal values, which is useful if your height was measured more precisely than to the nearest whole inch.
