1. Multiply feet by 30 (rough estimate)
2. Multiply inches by 2.5 (rough estimate)
3. Add them together

Example: 5'10" ≈ (5 × 30) + (10 × 2.5) = 150 + 25 = 175 cm (exact: 177.8 cm)

Quick shortcuts:
• 5'0" = 152 cm
• 5'10" = 178 cm
• 6'0" = 183 cm
• 6'2" = 188 cm

Formula Used

Converted value = Source value × Conversion factor
For affine conversions such as temperature, an offset is also applied.

How the formula is applied

The tool applies the relevant factor or temperature offset to the source value. Currency outputs require a current exchange-rate source, while cooking volume-to-weight conversions can vary by ingredient density and measuring method.

Calculator Description

The Feet and Inches to CM Converter is for converting heights/length which are set out in imperial units i.e. feet (ft) and inches (in) to metric i.e. centimeters (cm).Simply enter the required feet and inches and we provide you the centimeter (cm) measurement. Exact value for metric conversion i.e. 1 foot= 30.48 centimetersand1 inch = 2.54 centimeters.

How to Convert Feet and Inches to CM

To Convert feet and inches to centimetres: Convert all the feet into inches Add up all remaining inches to this total And then multiply this result by 2.54.

Total Inches = (Feet × 12) + Inches

Centimeters = Total Inches × 2.54

For example, 5 feet 8 inches equals 68 total inches. Multiplying 68 by 2.54 gives 172.72 cm.

Feet and Inches to CM Formula

The exact formula is:

CM = [(Feet × 12) + Inches] × 2.54

  • Feet = whole number of feet
  • Inches = additional inches
  • 12 = exact number of inches in one foot
  • 2.54 = exact number of centimeters in one inch
  • CM = resulting length or height in centimeters

An equivalent formula is:

CM = (Feet × 30.48) + (Inches × 2.54)

Both formulas produce the same result when calculated without intermediate rounding.

Feet and Inches to CM Example

Convert 5 feet 10 inches to centimeters.

Step 1: Convert feet to inches.

5 × 12 = 60 inches

Step 2: Add the remaining inches.

60 + 10 = 70 inches

Step 3: Convert inches to centimeters.

70 × 2.54 = 177.8 cm

Final result: 5 feet 10 inches = 177.8 cm

About Feet

The foot (abbreviated ft) is a unit of length in the U.S. Customary measurement system and the imperial measurement system. The foot is defined to be 12 inches exactly or 30.48 cm.

About Inches

The InchThe inch (abbreviated 'in') is the name for a unit of length which is most used in the United States. Precisely one inch is equal to 2.54 centimeters. When a measurement expressed in inches and feet, typically human height is expressed this way.

About Centimeters

Centimeter: Definition The abbreviation for the centimeter is cm. In the Metric System, there are 100 centimeters in a meter, and so 1 cm is 100 times smaller than 1 meter, and exactly 10 millimeters. It's likely that you've used centimeters to measure height, clothes or even to describe furniture!

Why Feet and Inches Must Be Converted Separately

Although the terms feet and inches are related, one does not represent the same numerical quantity as the other. There are exactly 12 inches in 1 foot. This is why you can’t get just a number out of an answer like 5′ 8″ by adding 5+8 multiplied by a conversion factor.

The correct approach is to convert both parts into a common unit first or convert each unit separately:

5 ft × 30.48 = 152.4 cm

8 in × 2.54 = 20.32 cm

152.4 + 20.32 = 172.72 cm

Feet and Inches to CM for Height Measurements

Height is typically represented in the U.S. in feet and inches, whereas heights are typically represented around the rest of the world in cm. 5' 6" = 167.64 cm, and 6' 2" = 187.96 cm.

Height Centimeters Approximate CM
5 ft 1 in 154.94 cm 155 cm
5 ft 3 in 160.02 cm 160 cm
5 ft 5 in 165.10 cm 165 cm
5 ft 7 in 170.18 cm 170 cm
5 ft 9 in 175.26 cm 175 cm
5 ft 11 in 180.34 cm 180 cm
6 ft 1 in 185.42 cm 185 cm
6 ft 3 in 190.50 cm 191 cm
6 ft 5 in 195.58 cm 196 cm
6 ft 7 in 200.66 cm 201 cm

How to Convert Feet and Inches to CM Without a Calculator

You can convert a feet-and-inches measurement manually using two simple conversion factors:

  • 1 foot = 30.48 cm
  • 1 inch = 2.54 cm

For a measurement such as 5 feet 7 inches:

5 × 30.48 = 152.4 cm

7 × 2.54 = 17.78 cm

152.4 + 17.78 = 170.18 cm

Therefore, 5 feet 7 inches = 170.18 cm.

Feet and Inches to CM vs. Decimal Feet

Important: Please Note Feet-and-inches is not the same as Decimal Feet Example: 5 Feet 6 Inches (or 5' 6") is NOT the same as 5.6 Decimal Feet. 5 Feet 6 Inches (5' 6") is the same as 5.5 Decimal Feet (as 6 Inches are half of 1 Foot).

To find out precisely, you can take the feet and inches separately as they are, or convert the entire measurement to inches first

Convert Feet and Inches to Total Inches

An alternative method is to convert the entire measurement to inches before converting to centimeters.

Total Inches = (Feet × 12) + Inches

For example, for 6 feet 4 inches:

(6 × 12) + 4 = 76 inches

Then convert inches to centimeters:

76 × 2.54 = 193.04 cm

Therefore, 6 feet 4 inches = 193.04 cm.

Rounding Feet and Inches to CM

The conversion process is an exact one, since one inch converts precisely into 2.54 centimeters, though the number may have a decimal in it. The decision whether or not to round may depend on the information in the metric calculation.

  • Nearest centimeter: useful for general height descriptions.
  • One decimal place: useful when moderate precision is needed.
  • Two decimal places: preserves the exact result for whole-inch measurements.

For example, 5 feet 8 inches equals exactly 172.72 cm, which can be reported as 173 cm when rounded to the nearest centimeter.

Common Input Mistakes

  • Confusing feet with inches: 5 feet 8 inches means 5 ft plus 8 in, not 58 inches.
  • Treating inches as decimal feet: 5 ft 6 in is not 5.6 ft.
  • Using 10 inches per foot: One foot contains exactly 12 inches.
  • Using an approximate conversion factor: 1 foot is exactly 30.48 cm and 1 inch is exactly 2.54 cm.
  • Rounding too early: Keep the exact conversion through the calculation and round the final result if necessary.
  • Entering centimeters as inches: Make sure the starting measurement is actually expressed in feet and inches.

Reverse Conversion: CM to Feet and Inches

After you get centimeters you just simply do dividing the number of centimeter by 2.54 will get you the number of total inches.

Total Inches = Centimeters ÷ 2.54

After dividing by 12, take your total answer. Take the whole number section of your answer and this is in feet, the remainder would be inches.

For example, 180 cm is approximately 70.87 inches. That corresponds to approximately 5 feet 10.87 inches.

The reverse conversion may require rounding because many centimeter measurements do not correspond to a whole number of inches.

Feet and Inches to CM for Forms and Applications

There are certain forms, profile fields, medical forms, team software, or international applications that require your height in centimeters even when you generally know your measurement in feet and inches. The calculator will do the job for you so you don’t have to make the calculation in two steps.

If the form asks for a whole number in centimeters, it usually has a box to tick to ask to have it rounded up instead of asking you to type in the decimal.
