Hint: In the given question, we have been given to convert one unit of measurement to another. We have to convert some given number of inches to centimeters. Here, we convert inches to centimeters by first writing the relation between a inch and centimeters and then multiplying by the given number of inches with it. It is thus important that we know how many centimeters there are in an inch.

Formula Used:
We are going to use the relation between inches and centimeters, which is,
\[1in = 2.5cm\]

Complete step by step solution:
We have to convert \[840\] inches to centimeters.
To do that, we multiply the conversion of one inch to centimeters by \[840\],
\[1in = 2.5cm\]
So, \[840in = 840 \times 2.5 = 2100cm\]

Additional Information:
Here, we converted inches to centimeters by first writing the relation between an inch and centimeters and then multiplying by the given number of inches. For the conversion of centimeters to millimeters, we multiply the given number of centimeters with ten. While, to convert meters to centimeters, we multiply by hundred.

Note: In the given question, we had to convert some given number of inches to centimeters. We need to know that the unit ‘inch’ is not a metric unit, so it cannot be converted to other such units by multiplying them with the power of ten. It is an imperial unit and so, we need to pay attention and specifically remember the conversion value so that we can convert it to other units and not get stuck.
