1 nm is equal to:
Show Hint
A nanometer is a unit of measurement used to measure atom size.
- $ 100\,\mu m $
10-8
10-3 mm
10 A0
The Correct Option is D
Approach Solution - 1
1 metre = 10-9 nm
1 metre = 10 10A0
1 nm = 10 A0
So, option D) is the correct answer.
Approach Solution -2
A nanometer is a small unit used to measure length.
1 nm = 10−9 m = 10 A0
Approach Solution -3
A nanometer is a unit of measurement used to measure atom size.
- The nanometer is also denoted by nm.
- Nanometer is used to measure the wavelength of light as well as the dimensions of atoms.
- 1 Angstrom (Å), 1 Å = 0.1 nanometer.
- A nanometer is one-billionth of a meter.
1 meter = 109 nm and 1 meter = 1010 A0
10-9 m = 10 x 10-10 m
So 1 nm = 10 A0

Units and Measurement
Unit:
A unit of a physical quantity is an arbitrarily chosen standard that is broadly acknowledged by the society and in terms of which other quantities of similar nature may be measured.
Measurement:
The process of measurement is basically a comparison process. To measure a physical quantity, we have to find out how many times a standard amount of that physical quantity is present in the quantity being measured. The number thus obtained is known as the magnitude and the standard chosen is called the unit of the physical quantity.
