what is 68 nm in meters

Question

Help plz 

Answer 1

1 nm = 1 x 10^-9 m

68 nm = 68 x 10^-9 m

68 nm = 6.8 x 10^-8  m

Answer 2

68 nm written out is:

68 nanometers.

 

We need to convert nanometers to meter. In order to do this, we need to know how many nanometers there are in 1 meter.

 

So...

"millimeter" means 1 thousandth of a meter.
"micrometer" means 1 millionth of a meter.

Well, 1 "nanometer" means 1 billionth of a meter.

 

the prefix nano tells us this.

 

How do we calculate 1 billionth of a meter? We just take 1, and divide it by 1 billion!

 

This gives us 1 / 1,000,000,000.

 

If we calculate 1 / 1,000,000,000 we get 0.000000001.

 

So 1 nanometer is 0.000000001.

 

The only problem here is that we don't want just 1 nanometer, we want 68 nanometers.

 

That means we want 68 multiplied by 1 nanometer. This gives us:
0.000000001 * 68 = 0.000000068.

 

So 68 nanometers in meters is just 0.000000068.
