Question

Convert 4.57X-3m to the equivalent length in nanometers

Answer 1

Answer:

                       4.57 × 10⁶  nanometers  

Explanation:

                    In this problem we are asked to convert between two units i.e. a meter into nanometer. In sciences, the different units are used for a same quantity (achieved by multiplying conversion factors) to get rid of very small values and get a readable and  intelligible values.

For Example:

In given statement the value of small distance is 4.5 × 10⁻³ meter the real number form of this number is 0.00457. Hence, this number can be converted to a very large number by multiplying it with 10⁹ or 1000000000. Hence,

                         4.5 × 10⁻³  × 1.0 × 10⁹  =  4.57 × 10⁶

Or,

                 4.5 × 10⁻³  meters  =  4.57 × 10⁶  nanometers    

Although the quantity is the same for same units but the number has changed.
