Question

Convert \[1.4\text{ }m\text{ }98\text{ }cm\] into \[cm\].

Answer 1

Hint: To solve this question, we must know that a meter comprises \[100\text{ }cm\] . To convert the given length into \[cm\] , Go through the conversion table for length. Convert meter into centimeter. And then add the remaining centimeters to the already found value.

Complete step by step answer:
 You need to understand the following terms well,
1. Kilo is equivalent to a thousand.
2. Milli is equivalent to a thousand.
3. Centi is equivalent to a hundred
4. Deci is equivalent to ten.
Hence, we can do the following length conversions as per the terminologies shown previously.
We can write,

1000 meters(m)	1 kilometer(km)
1 meter(m)	1000 millimeters(mm)
1 meter(m)	100 centimeters(cm)
1 meter(m)	10 decimeters(dm)

Hence, it should be clear that 1 meter (m) = 100 centimeters (cm).

Having said that, let's look at the questions at hand.
We need to convert 1.4 m 98 cm into only centimeters. As we can consider both separately, we can first convert 1.4 meters into centimeters and then add the 98 cm to get the final answer.
We know that,
\[\begin{align}
  & 1m=100cm \\
 & \Rightarrow 1.4m=(1.4\times 100)cm=140cm \\
\end{align}\]
Hence, when we can add the \[98\text{ }cm\] to the value we have found previously, to get the final answer.
\[(140+98)cm=238cm\]

Hence the conversion result is \[238cm\] .

Note:
1) You need to remember the conversion table before attending this kind of question. It will be beneficial for you, and you will avoid any unnecessary mistakes.
2) Always remember the conversion table that we have shown. All the units are useful for different purposes.
3) In kinematics or speed related problems, km/h is a crucial unit, and you should be able to convert it into m/s. Knowing the conversion is important because the calculation has to be done in the SI system.
4) A decimeter is important because the popular unit of volume - Litre is the third power of the decimeter. Centimeters and Millimeters are also two crucial units for measuring small dimensions.
