Converting between different units of length can be quite confusing, especially when you are dealing with measurements that are not commonly used in your daily life. However, with a little bit of knowledge and practice, you can easily convert between units and make your life a lot easier. In this case, we will be converting from centimeters (cm) to inches (in) by using the conversion factor of 1 cm = 0.393701 in.
Step 1: Understand the Conversion Factor
Before we begin the conversion, it is important to understand the conversion factor that we will be using. The conversion factor is simply a ratio that relates the two units of measurement. In this case, 1 cm is equivalent to 0.393701 in. This means that for every 1 cm, there are 0.393701 inches.
Step 2: Write Down the Given Measurement
The first step in any conversion is to write down the given measurement. Let’s say we have a length of 25 cm that we want to convert to inches.
Step 3: Set Up the Conversion Equation
To convert from cm to in, we will use the conversion factor in the form of an equation:
25 cm x (0.393701 in / 1 cm).
Step 4: Cancel Out Units
To cancel out the cm unit, we will multiply the given measurement of 25 cm by the ratio of 0.393701 in / 1 cm. This will give us a new measurement in inches.
25 cm x (0.393701 in / 1 cm) = 9.842525 in
Step 5: Round Up
In this final step, we can round up the measurement to the appropriate number of significant figures. In this case, we round to the nearest tenth, giving us a final measurement of 9.8 in.
Congratulations! You have successfully converted 25 cm to inches. Whenever you need to convert between units of length, simply follow these steps and you’ll be able to convert with ease.
