How many nanometers is one meter?

0.000 1 km = 1 decimeter (dm)

0. 1 m = 1 decimeter

10cm = 1 decimeter (decimeter)

100 mm = 1 decimeter (decimeter)

10 decimeter (dm) = 1 meter (m)

0. 1 decimeter (dm)= 1 cm.

0.0 1 decimeter (dm) = 1 millimeter (mm)

Nanometer units of length, such as centimeters, decimeters and meters, are all units of length measurement. It is four times the size of an atom and much smaller than the length of a single bacterium. The international common name is nanometer, abbreviated as nm.

A single bacterium is invisible to the naked eye, and the diameter measured by microscope is about five microns. Suppose that a hair has a diameter of 0.05 mm and is cut into 50,000 pieces on average along the axial direction, and the thickness of each piece is about 1nm. In other words, 1 nm is 0.00000 1 mm.

The definition of "meter" originated in France. The length of 1 meter was originally defined as one ten thousandth of the distance from the equator of the earth to the north pole on the meridian passing through Paris, and then the international meter origin was determined. With the deepening of people's understanding of measurement, the definition of the length of meter has been revised several times.

Extended data:

A centimeter is a unit of length measurement, equal to one hundredth of a meter. The unit of length, abbreviated as cm. ， 1cm = 1/ 100m。 1cm (cm) = 10mm (mm) =0. 1dm (decimeter) =0.0 1m (meter).

The international system of units chooses seven independent quantities as the base quantity, and the first one is length. Its basic unit name is meter, the symbol is m, and centimeter is not an international unit.

The unit of length refers to the basic unit for measuring spatial distance, which is formulated by human beings to standardize the length. Its international unit is "meter" (symbol "m"), and commonly used units are millimeter (mm), centimeter (cm), decimeter (dm), kilometer (km), meter (m), micron (micron) and nanometer (nm). Length units play an important role in various fields.
