    How many Nanometers equal one Millimeter?

Millimeters (mm) and nanometers (nm) are units derived from the meter. According to the treaty signed by the International System of Units (SI) in 1959, 1 millimeter is equivalent to 1,000,000 nanometers, i.e 1 nanometer is 0.000001 of a mm.

    Difference between Millimeters and Nanometers

The millimeter is 1/1,000 the size of a meter, therefore it can be defined as being equal to the path that light travels in 1/299,792,458,000 seconds in vacuum.

The millimeter is a unit that measures small lengths, but is still practically applicable to most situations. Of course, it is preferred in cases where accuracy is of great importance, such as mechanics or engineering. For example, the wavelength of 300 GHz microwave ovens is 1 millimeter.

Nanometers, however, are as small as being one-millionth the size of a millimeter. Needless to say, they are a unit used in extremely specific situations and fields that measure microscopic scales. Science branches dedicated to examining and manipulating atomic-sized objects are given the prefix ‘nano’ – e.g. nanotechnology.

    How to convert Millimeters to Nanometers

Converting millimeters to nanometers is as simple as knowing the relationship between the two units. You can place the decimal point in the mm 6 positions to the right, or simply use the formula:

mm x 1,000,000 = nm.

Mm to nm conversion example

Sample task: convert 50 millimeters to nanometers. Solution:

mm * 1000000 = nm
50 mm * 1,000,000 = 50,000,000 nm
End result:
50 mm is equal to 50,000,000 nm
