nanometer conversion

[Daniela Santana 2L]

Does anyone know how to convert meters to nanometers?

I'm not sure how to convert it and in a lot of the problems I see it seems like you just have to move the decimal place over?

Example: 4.2x10^-7 m converts to 420 nm

Is there an actual method to convert it or is it just moving the decimal place over?

The conversion from meters to nanometers is:
1 m = 1 x 10^9 nm

To convert from meters to nanometers, multiply your value of meters but 10^9 and that will give you the value in nanometers.

The conversion is 1 m = 10^9 nm. I think about it as moving the decimal place over, and I do the conversion in my calculator. Hope this helps!

One meter is equal to 1x10^-9 nanometers, so to convert from meters to nanometers you would multiply the value by 10^9.

In the example you gave, 4.2X10^-7 m becomes 420 nm by multiplying the value in meters by 10^9.

In order to convert from meters to nanometers you would have to multiply the figure that has been presented by 1,000,000,000 (10^9).

The way to convert any kind of units, whether converting from one unit to a different unit, or from one prefix of unit, to a different unit, is by using conversion factors.

Conversion factors are basically fractions of some unit "x" to some unit "y".

for example, if 1 unit x = 2 unit y, we can set up a conversion factor to find units y from units x.

Suppose we are given 2 units x, and want to find how many units of y we have from this.

We can do this by doing the following: 2 units x * (2 units y) / (1 unit x). Notice that the x units cancel by being divided out!

The same principles can be applied to converting to nanometers.

4.2 * 10 ^-7 m * (1 nm) / (10^-9 m) = 4.2 * 10^2 nm <---- The prefix "nano" means 10^-9. This is why one nanometer = 10^-9 of a meter. It's a good idea to memorize your prefixes.

Hope this helped!

What equation only uses nanometers to get an answer?
