HOW SMALL IS NANO

Macrosize

 

Child

A child is about 1 meter tall

1 meter = 1,000,000 nm (1 billion nanometers)

 

Hand

A hand is about 1 decimeter wide

1 decimeter = 100,000,000 nm (100 million nanometers)

 

Pinky Finger

A pinky finger is about 1 centimeter wide

1 centimeter = 10,000,000 nm (10 million nanometers)

 

Freckle

A freckle is about 1 millimeter wide

1 millimeter = 1,000,000 nm (1 million nanometers)

 

Stand of Hair

A hair is about 0.1 (one tenth) of a millimeter wide

0.1 millimeter = 100,00 nm (100 thousand nanometers)

 

Microsize

 

Red Blood Cell

A red blood cell is about 10 micrometers wide

10 micromters = 10,000 nm (10 thousand nanometers)

 

Bacteria

A bacteria cell is about 1 micrometer wide

1 micrometer = 1,000 nm (1 thousand nanometers)

 

Virus

A virus is about 0.1 (one tenth) of a micrometer wide

0.1 micrometer = 100 nm (1 hundred nanometers)

Nanosize

Cell Membrane

A cell membrane is about 10 nanometers wide

10 nanometers = 10 nm

Sugar Molecule

A sugar molecule is about 1 nanometer wide

1 nanometer = 1 nm

Atom

An atom is about 0.1 (one tenth) of a nanometer wide

0.1 nanometer= 0.1 nm
