Convert 12 cm into inches.
Understand the Problem
The question is asking for a conversion of a measurement from centimeters to inches. To do this, we will use the conversion factor that 1 inch is equal to 2.54 centimeters.
Answer
To convert centimeters to inches, use $I = \frac{C}{2.54}$.
Answer for screen readers
The answer will be calculated based on the specific number of centimeters you provide.
For example, if converting 10 cm, the answer would be: $$ I \approx 3.94 \text{ inches} $$
Steps to Solve
- Identify conversion factor
We know from the problem that 1 inch is equal to 2.54 centimeters. To convert centimeters to inches, we can use the conversion factor:
$$ 1 \text{ inch} = 2.54 \text{ cm} $$
- Set up the conversion
Let's denote the number of centimeters you want to convert as $C$. To convert centimeters to inches (let's denote it as $I$), we can set up the equation:
$$ I = \frac{C}{2.54} $$
- Perform the calculation
Now, substitute the value of $C$ (the number of centimeters) into the equation and divide by 2.54 to find the number of inches.
- Example calculation
If $C = 10$, then:
$$ I = \frac{10}{2.54} \approx 3.94 \text{ inches} $$
The answer will be calculated based on the specific number of centimeters you provide.
For example, if converting 10 cm, the answer would be: $$ I \approx 3.94 \text{ inches} $$
More Information
Conversions between centimeters and inches are common in many fields, especially in contexts involving measurements for clothing, construction, and scientific research. Remembering the conversion factor of 2.54 is helpful for quick calculations.
Tips
- Forgetting to divide by the conversion factor; always ensure to use the correct operation (division) when converting from cm to inches.
- Confusing the conversion factor (using 2.54 cm per inch instead of the inverse); keep in mind the relationship of inches to centimeters.
