Step 1: Understand the Measurements
Before we begin, let’s make sure we understand the two units of measurement we will be using. Centimeters (cm) and inches (in) are both units of length, but they are used in different systems of measurement. Centimeters are part of the metric system, while inches are part of the imperial system.
Step 2: Write Down the Given Measurement
In this case, the given measurement is 18cm. Write this down on a piece of paper or on your calculator, so you do not forget.
Step 3: Determine the Conversion Factor
To convert from centimeters to inches, we need to use a conversion factor. The conversion factor for centimeters to inches is 2.54. This means that 1 centimeter is equal to 2.54 inches.
Step 4: Set Up the Conversion Equation
Now that we have our conversion factor, we can set up the conversion equation. The general formula for converting from one unit to another is: converted value = given value x conversion factor. In this case, our equation will be: 18cm x 2.54.
Step 5: Simplify the Equation
To get the final answer, we simply need to multiply 18cm by 2.54. This can be done on a calculator or by hand. The result of this multiplication is 45.72, which means that 18cm is equal to 45.72 inches.
Step 6: Write the Answer
Remember to always include the unit of measurement with your answer. Therefore, our final answer is: 18cm = 45.72 inches.
Step 7: Check Your Work
It is always a good idea to double check your work to ensure accuracy. In this case, we can check our answer by dividing 45.72 inches by 2.54. The result of this division is 18cm, which means our answer is correct.
Congratulations! You have successfully converted 18cm to inches. Keep in mind that this method can be used to convert any value from centimeters to inches. Just remember to always find the conversion factor and follow the steps above.
