Question

How many meters in one nanometer?

Answer 1

Hint :There are many units in physical world such as kilometres (km), meters (m), centimetre (cm), millimetre (mm), nanometre (nm), and decametre (dm). To answer this question you should have the proper knowledge of conversions. The one conversion from one of them is been discussed in the section below:

Complete Step By Step Answer:
As we know that nanometre is the unit which is used to measure length in a metric system. It is equal to the one billionth of a metre $\left(0.000,000,001m\right)$ . If you want to denote it in scientific notation, then its scientific notation can be written as $1\times {10}^{-9}m$ or it can be written as ${\displaystyle \frac{1}{1,000,000,000}}$ metres. If we interchange the question that is we want to find that how many nanometres are there in one metre, then the answer of this question will be that one metre is equal to the one billion nanometre and its scientific notation can be written as $1\times {10}^{9}nm$ or it can be written as $1,000,000,000$ nanometres. There are many more conversions such as one meter is equal to hundred centimetres. Its scientific notation can be written as $1m=1\times {10}^{2}cm$ or it can be written as $1m=100cm$ both are the same.

Note :
The earlier name of nanometer was millimicrometre but it is not common. The more common name of nanometers was millimicron. If we write the scientific relation between nanometer and millimicron then it will be $1nm=1\times {10}^{-3}$ (micrometre) or it can be written as $1nm={\displaystyle \frac{1}{1000}}$ (micrometer). As we can clearly see that it is a very small value, so to measure it we need a more precise and advanced calculator.
