Converting m to nm

[KiaraTenorio_14B]

When i was converting m to nm for the wavelength on problem #8 of the achieve homework I continued to get a answer with a negative exponent. When you are converting from m to nm do you divide or multiply by (1x10^-9)?

[Andrew Nguyen 2K]

When converting from meters to nanometers you would have to multiply by 1 x 10⁹.

[Lulu Almoshawah_2K]

you multiply the meters by 1 x 10^9 to get the nm

[Nithya Madhu 2L]

Hey! To convert from meters to nanometers you would multiply by 10^9. A good way to remember is by using units when converting. You know 1 m is 10^9 nm. Then to covert from m to nm, you do __m * (10^9 nm / 1 m). This way the m cancels out and you are left with nm. Hope that makes sense!

[Shania Garrison Discussion 3E]

1 nm is 1 x 10^-9 m. So you can say you have 2 nm, you can convert this to m by doing: 2 nm x ((1 x 10^-9 m)/1 nm).

[Angela Harrington 2L]

To convert from meters to nanometers, you would have to multiply by 1 x 10^9.

[Jamie Park 2F]

Since nm are smaller units than m, you would need to multiply by 1 x 10^9.

[Rhea Jain 2I]

To convert m to nm, you multiply by 10^9. Try and remember that nanometers are much smaller than m, so the number becomes much larger when converting m to nm.

[105778693]

You would multiply by 1 x 10^9 in order to cancel out the m and get nm in your final answer.

[Carly Yoon]

You would multiply by 10^9 because nm are smaller than m, so it makes sense that you would end up with a larger number for nm than m.

[Benjamin Nguyen 1J]

To convert from meters to nanometers, multiple by 10⁹

[Olivia Peony Dis 2A]

Hi! So a good way to remember is that nm is a smaller unit than m, hence if I have 1 m, converted to nm, the number must be bigger in nm. Hence we multiply anything from meter by 10^9 to get a number in nm. To sumarize:
1 Gm = 10^9 m
1 Mm= 10^6 m
1km = 10^3 m
1m
1mm=10^-3 m (hence 1 m = 1/10^-3, 10^3 mm)
1micrometer=10^-6m
1 nm = 10^-9 m
1pm=10^-12 m
Most likely, you will convert other prefixes to meters, so just multiply any number with that prefix by the powers of ten on the right to get in meters. And divide anything from meters to get anything in the prefixes using the same powers of 10.

Hope this helps :)

Hey! You would need to multiply by 1 x 10^9.

[Jason Ho 2L]

You would either multiply by 1x10^9 or divide by 1x10^-9.

[Aaron Tang 2F]

If you ever get confused doing a unit conversion, use a dimensional analysis, as that is a methodical way to get the correct unit conversion. For example, I know 1 m is 10^9 nm. I do the fractions: , and know that to cancel out meters and get nanometers, I have to multiply by 10^9. Doing the crossing out provides a surefire way to convert units correctly.

[Erin Chin 1L]

Hi there! Since nm is smaller than m, you multiply by 1 x 10^9. For me, when doing unit conversions, I find it helpful to do dimensional analysis so that you can cross out units and keep track of them easily. It's especially helpful when you're dealing with multiple units. Hope this helps.

[Rebecca Preusch 2C]

You would multiply nanometers by 10^-9 to get meters.

[Kirsten Yu 2K]

multiply the number of meters by 10^9 to convert to nanometers

[205819952]

To get the nm, multiply the meters by 1 x 10^9.

[Ryan Lafferty 1L]

To go from m to nm, you must multiply by 1*10^-9

[Caitlin Beale 3E]

10^-9 meters = 1 nanometer. We use this equation and apply it to our stoichiometry problems.

[Tyler Olson 1E]

To turn meters into nanometers you would multiply the value in meters by 10^9.

[Ainsley DeMuth 1H]

On our equations sheet provided by Lavelle, you can find an equation for the conversion of nm to m. I find it most useful to set up ratios and convert the units from there. When you set up a ratio nm/m, you will end up dividing the m by 10^-9 which is the same as multiplying by 10^9. By using the ratios, a clearer picture can be seen as to why this is the case.

[Hailey Jeon]

In order to convert m to no, you multiply 10^-9 or divide 10^9

[Zara Okeiyi 3C]

You would multiply by 1 X 10^9

[Saebean Yi 3E]

For these types of questions, even if it looks simple, I always use dimensional analysis. While it might look overkill, I think it almost guarantees that you don't accidentally divide or multiply the wrong way.
It basically allows you to visually cancel out the units, while doing the same thing everyone is mentioning (multiplying by 10^9).

[Ariella Sassover 3A]

There are 10^-9 nm for every 1 m. Thus when converting nm to m multiply the nm amount by 10^-9.

[Madeline_Miller]

Hey! A quick way to do this conversion is to just add #*10^-9.

[Alexis Rempillo 3B]

We will need to multiply the value of the m by 1 * 10^-9. Nano- meaning 10^-9.
EX: Convert 3 nm to m:
3 x 10^-9

[Ryan Lafferty 1L]

Multiply by 1x10^-9

[Omeed Kalan]

Just do x10-9

[Harshitha_Pandian_3F]

The way I look at converting units is by multiplying the amount given by 10 to the power of -9 if you are converting from nm to m and 10 to the power 9 if you are going from m to nm.

[105707059]

You multiply the meters by 1 x 10^9 :)

[Lizzy Bulla 3K]

When you convert meters to nanometers you should be multiplying by 10^9

[Brianna Mercado 3D]

Hi! You need to multiply by 1 x 10^9 in order to cancel out the m and get nm

[Sally_Luo_3F]

you would have to multiply the value by multiply by 1 x 10^9 to get nm.

[Maia Holmes Kueny 1C]

When you are converting m to nm, multiply by 10^9. When you are converting nm to m, multiply by 10^-9.

[605537776]

1 nm = 1 x 10^-9 m
