There are many inches (“) to centimeters (cm) converters available online, all of which claim that 1 inch = 2.54 cm . Your teacher will ask you to explain the calculation. Fortunately, converting inches to centimeters using algebraic steps and then dropping the appropriate units is simple. If the original data is in inches, you just need to replace the value in the space in the simple formula below and do the calculation.See step 1 below to get started.
Steps
Convert with simple math
Convert with detailed explanation
- To convert 6’2″ to cm, we need to multiply 6 feet by 12 inches to make 72 inches. Then take 72 inches plus the 2 available inches to get the final value of 74 inches .
| ____ |
* | 2.54 cm 1 |
= | ? cm |
This conversion factor will help you find the correct answer in centimeters and meet most “presentation” requirements (if you are a student). Just replace the inch value in the blank at the beginning of the conversion factor and do the multiplication.
- This formula will also get you the correct units . Note: the “inch” in the denominator will be reduced by the “inch” of the value you substitute, the final answer will only be “cm” in the numerator of the formula.
- Try substituting 74 inches in the conversion factor.
- (74 inches × 2.54 cm)/(1 inch)
- (187.96 inches × cm)/(1 inch)
- Remove the “inches” since they appear twice in both the numerator and the denominator, so we are left with a final answer of 187.96 cm .
- For example, to convert 6 inches to centimeters, we only need to calculate 6 × 2.54 = 15.24 cm .
- For example, let’s convert 31 inches to centimeters using the quick calculation method:
- 2.5 × 30 = 75. 2.5 × 1 = 2.5
- 75 + 2.5 = 77.5 cm .
- Note: if you use the exact conversion factor of 2.54 centimeters/1 inch, the answer will be 78.74 cm . These two answers have a difference of 1.24 cm (about 1.5%).
Advice
- 1 inch = 2.5399999 cm, so 2.54 cm = 1 inch is very accurate because:
- As a scale, 1 cm = 0.39370079 inches or “1 cm / 0.39370079 inches”, which approximates 4/10 inches = 1 cm.
