To convert centimeters to inches, you can use the following formula:
inches = centimeters / 2.54
Now, let’s convert 48cm to inches:
inches = 48 / 2.54
inches = 18.8976
Therefore, 48cm is equal to approximately 18.8976 inches.
Real-life example:
If you have a ruler that measures in centimeters and you want to know how many inches a certain length is, you can use the conversion formula to easily find out. For example, if you measure an object to be 20cm long, you can convert it to inches by dividing 20 by 2.54 to get approximately 7.874 inches.
FAQs:
1. Why do we need to convert units?
Converting units allows us to easily compare measurements in different systems and use them in different contexts. For example, if you have a recipe that uses metric units but you are more familiar with imperial units, converting the measurements can help you follow the recipe accurately.
2. Can I convert units without using a formula?
While it is possible to convert units using online converters or conversion tables, understanding the formula and the process can help you do it manually and have a better grasp of the concept.
3. Is the conversion factor always the same for all units?
No, the conversion factor can vary depending on the units being converted. For example, the conversion factor for centimeters to inches is 2.54, but the conversion factor for kilometers to miles is different. It’s important to use the correct conversion factor for accurate results.
