Converting Heights Between Metric and Imperial

This free online height converter provides an effortless way to translate any measurement from centimeters to feet and inches. Built for quick switching between the metric system and US customary units, the tool works instantly for both common and custom values — whether you’re checking someone’s height or handling a construction dimension. Simply enter a value and receive the equivalent in both feet and inches.

Understanding the Base Units

Centimeters (cm) belong to the International System of Units (SI). One centimeter equals exactly 0.010.01 of a meter, so a meter contains 100 centimeters.

Feet and inches are used in the US customary and imperial systems. A foot (ft) is defined as 12 inches (in), making the two units complementary when describing heights (e.g., 5 ft 10 in). The exact conversion constants that bridge the two systems are:

1 ft=30.48 cm,1 in=2.54 cm. 1\ \text{ft} = 30.48\ \text{cm}, \qquad 1\ \text{in} = 2.54\ \text{cm}.

These fixed relationships are the foundation of all cm‑to‑ft‑in conversions.

Converting Centimeters to Feet and Inches

To change a length from centimeters to feet and inches, follow these steps:

  1. Divide the value in centimeters by 30.48 to get the total number of feet (including the decimal part).
  2. Take the integer portion of that result — this becomes the whole‑feet component.
  3. Multiply the decimal remainder by 12 — the product gives the inches.

Using formulas:

ft=⌊cm30.48⌋,in=(cm30.48−ft)×12. \text{ft} = \left\lfloor \frac{\text{cm}}{30.48} \right\rfloor, \qquad \text{in} = \left( \frac{\text{cm}}{30.48} - \text{ft} \right) \times 12.

Example: Convert 78 cm.

78÷30.48≈2.55978 \div 30.48 \approx 2.559

  • Whole feet: 22
  • Remainder: 0.559×12≈6.710.559 \times 12 \approx 6.71

So 78 cm is approximately 2 ft 6.7 in.

Converting Feet and Inches to Centimeters

The reverse conversion is equally straightforward:

  1. Divide the inches part by 12 to express it as a decimal fraction of a foot.
  2. Add this fraction to the whole‑feet value.
  3. Multiply the total (now in decimal feet) by 30.48.

In formula form:

cm=(ft+in12)×30.48. \text{cm} = \left( \text{ft} + \frac{\text{in}}{12} \right) \times 30.48.

Example: Convert 5 ft 10 in into centimeters.

decimal ft=5+1012=5.8333\text{decimal ft} = 5 + \frac{10}{12} = 5.8333
5.8333×30.48≈177.8 cm5.8333 \times 30.48 \approx 177.8\ \text{cm}

Thus 5 ft 10 in is about 178 cm.

Why an Online Converter Helps

Performing the arithmetic manually is certainly possible, but a dedicated cm to ft in converter eliminates the risk of rounding mistakes and returns results in a split second. The tool is free, requires no installation, and works on any device — simply type a number (or slide a scale) and the equivalent feet‑inches pair appears instantly. Whether you need a height converter cm to feet for everyday use or a reliable metric to imperial height converter for technical work, this calculator handles the job with minimal effort.

The combination of instant feedback, pre‑built formulas, and clear unit separation makes it the most convenient way to switch between centimeters and the feet‑inches system.

FAQ

1. How do I convert centimeters to feet and inches?

Divide the measurement in centimeters by 30.48. The integer part of the result gives the whole feet. Multiply the decimal remainder by 12; that product is the inches. For example, 170 cm ÷ 30.48 ≈ 5.577, so 5 ft and 0.577 × 12 ≈ 6.9 in, giving 5 ft 6.9 in.

2. How do I convert feet and inches back to centimeters?

Divide the inches by 12, add that decimal to the whole feet, then multiply the sum by 30.48. For instance, 5 ft 10 in = (5 + 10/12) × 30.48 ≈ 177.8 cm.

3. Why is 30.48 used in the conversion formula?

30.48 comes from the fact that 1 foot = 12 inches and 1 inch = 2.54 cm. Multiplying 12 × 2.54 gives 30.48 – the exact number of centimeters in one foot.

4. Is 178 cm equal to 5 feet 10 inches?

Yes. 178 ÷ 30.48 ≈ 5.84 ft, and 0.84 × 12 ≈ 10.1 in. So 178 cm is about 5 ft 10 in, which is a very close match.
