What measurement best describes the results of a scientific experiment regarding distance?

Answer 1

Most scientific experiments measure distance in the metric system. Therefore, millimeter, centimeter, meter and kilometers are commonly seen. Occasionally, inches and miles are seen as measurements in school experiments in the United States.

Answer 2

Scientists use many units for measuring distances as the case may be.

Of course the unit of distance in SI system is meter.

But when we measure large distances as the distance between the sun and a planet, scientists use Astronomical unit which is nothing but the distance between the sun and the earth. 1 Astronomical unit is 1.486 x 1011 m

As the diameter of the galaxies or distance between stars, unit light year is used.

1 light year is the distance travelled by light in one year. This equals to 9.467 x 1015 m

Apart from these two, sometimes another unit is also used known as parsec.

Now as we have to measure smaller distances, just for convenience scientists have taken nm, Angstrom, micron, fermi etc.

1 nm = 10 -9 m and 1 Angstrom = 10 -10 m. Both are used in dealing with the wavelengths of electromagnetic waves such as visible light, X rays etc.

Micron is 10 -6 m which is used to state the diameter of hair etc

Fermi is 10 -15 m which is mostly applicable when we deal with the radius of the atomic nuclei.
