Height Converter Calculator (to Centimeters)
Enter your height in feet/inches, inches, or meters and get instant conversion to centimeters (cm).
Why calculate height in cms?
Centimeters are one of the most common units for recording body height in health records, school forms, sports registrations, and international documents. If you grew up using feet and inches, converting to centimeters can feel annoying at first. The good news is that once you know the formulas, the process is simple and fast.
Using centimeters also makes comparisons easier because the metric system is base-10. Instead of juggling two units (feet and inches), you work with one clean number.
Quick conversion formulas
Feet and inches to cm
Use this formula:
Height (cm) = (feet × 30.48) + (inches × 2.54)
Example: 5 ft 8 in
- 5 × 30.48 = 152.40
- 8 × 2.54 = 20.32
- Total = 172.72 cm
Inches to cm
Height (cm) = inches × 2.54
Example: 70 inches → 70 × 2.54 = 177.8 cm
Meters to cm
Height (cm) = meters × 100
Example: 1.82 m → 1.82 × 100 = 182 cm
Common height conversions
- 4 ft 10 in = 147.32 cm
- 5 ft 0 in = 152.40 cm
- 5 ft 4 in = 162.56 cm
- 5 ft 8 in = 172.72 cm
- 6 ft 0 in = 182.88 cm
- 6 ft 2 in = 187.96 cm
How to measure your height accurately
If your input is wrong, your conversion will also be wrong. Use these tips for a better measurement:
- Stand against a flat wall without shoes.
- Keep your heels, hips, and upper back as close to the wall as possible.
- Look straight ahead (not up or down).
- Place a flat object (like a hardcover book) on top of your head, level with the floor.
- Mark the wall and measure from floor to mark.
When centimeters matter most
Converting height to cm is useful in many real-world settings:
- Medical records: Clinics commonly use centimeters for BMI and growth tracking.
- Travel and immigration forms: Many forms request metric values.
- Sports and fitness: International programs often prefer cm and kg.
- Education: School health files are frequently stored in metric units.
