## What is the relationship between M and nm?

Nanometers and meters are based on units of 10 (like the whole of the metric system), so converting between units is really about moving the decimal. Because 1,000,000,000 nm equals 1 m, converting from nanometers to meters consists of simply moving the decimal point to the left nine places.

**What is M and nm in chemistry?**

n = m/M n is the amount of substance, in moles, mol. m is the mass of the substance, in grams, g.

**How do you convert from nm to M?**

There are 1e-9 meters in 1 nanometer. To convert from nanometers to meters, divide your figure by 1000000000 .

### What is an nm measurement?

A nanometer is a unit of measurement for length just as you have with meters and centimeters. A nanometer is one billionth of a meter, 0.000000001 or 10-9 meters. The word nano comes from the Greek word for “dwarf.” The term nanoscale is used to refer to objects with dimensions on the order of 1-100 nanometers (nm).

**What does NM mean in concentration?**

A nanomolar (nM) is the decimal fraction of a molar, which is the common non-SI unit of molar concentration. For example, a 2-molar (2 M) solution contains 2 moles of a certain substance in one liter of a liquid or gaseous mixture.

**What conversion factor would you use to convert nanometers to kilometers?**

The length in kilometers is equal to the nanometers divided by 1,000,000,000,000.

#### What is a dimensional analysis in math?

Dimensional Analysis. Dimensional Analysis (also called Factor-Label Method or the Unit Factor Method) is a problem-solving method that uses the fact that any number or expression can be multiplied by one without changing its value. It is a useful technique.

**How do you convert nm to m?**

Solution: 1 meter = 10 9 nanometers. Set up the conversion so the desired unit will be canceled out. In this case, we want m to be the remaining unit. distance in m = (distance in nm) x (1 m/10 9 nm) Note: 1/10 9 = 10 -9. distance in m = (632.1 x 10 -9) m.

**What is the formula for the length of a nm?**

length in nm = (length in m) x (10 9 nm/m) Note the meters unit cancels out, leaving nm. length in nm = (7.5 x 10 -7) x (10 9) nm. or, you could write this as: length in nm = (7.5 x 10 -7) x (1 x 10 9) nm. When you multiply powers of 10, all you need to do is add together the exponents.

## How long is 1000000000 nm in meters?

The answer is 1.0E-9. We assume you are converting between metre and nanometre. The SI base unit for length is the metre. 1 metre is equal to 1 m, or 1000000000 nm. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between metres and nanometres.
