Converting units of length can be a daunting task for some, but with a little know-how, it can be done easily. In this case, we will be converting 19cm to inches.
Step 1: Know the conversion factor
In order to convert from one unit to another, we need to know the conversion factor. For converting cm to inches, the conversion factor is 2.54 cm = 1 inch. This means that for every 2.54cm, there is 1 inch.
Step 2: Set up the equation
To convert from cm to inches, we will use the equation:
(19 cm) x (1 inch/2.54 cm) = x inches
Here, x represents the number of inches.
Step 3: Cancel out the common units
In this equation, we can see that cm is present on both sides. This means that we can cancel it out. So, we are left with:
19 x (1 inch/2.54) = x inches
Step 4: Solve the equation
Solving the equation, we get:
7.48 inches = x inches
This means that 19cm is equivalent to 7.48 inches.
Step 5: Round off the answer
In most cases, the answer will not be a whole number. To get a more practical value, we can round off the answer to the nearest hundredths place. In this case, we get 7.48 inches rounded off to 7.5 inches.
Step 6: Final answer
Therefore, 19cm is equal to 7.5 inches when converted.
In conclusion, converting units of length can be done easily by knowing the conversion factor and setting up the equation. By following these simple steps, you can convert any unit of length with ease.
