Question

How many nanometers are there in 1 cm?

Answer 1

`1` centimeter has `10,000,000` i.e. `10` million nanometers.

Explanation:

Standard unit in this system is `1` meter.

There are a billion i.e. `1,000,000,000` nano units in a standard unit and hence `1,000,000,000` nanometers in one meter.

As there are `100` centimeters in each meter,

`1` centimeter has `(1,000,000,000)/100=10,000,000` i.e. `10` million nanometers.
