Dekameter
A dekameter (dam) is a unit of length in the metric system, equal to 10 meters. It sits between a meter and a hectometer in size. Although it is an official part of the metric system, the dekameter is rarely used in everyday life, education, or even science. For example, a small swimming pool might be around 2 dekameters long. The symbol for dekameter is "dam". Since most people prefer using meters or kilometers, the dekameter is more of a theoretical unit used mainly for teaching the structure of the metric system.
Ångström
An ångström (symbol: Å) is a unit of length commonly used in physics, chemistry, and biology to measure very small distances, such as atomic and molecular scales. It is equal to 10⁻¹⁰ meters, or 0.1 nanometers (nm).
The unit is named after the Swedish physicist Anders Jonas Ångström, who made significant contributions to spectroscopy.
Key facts:
1 ångström = 10⁻¹⁰ meters = 0.1 nanometers
Used to measure atomic and molecular sizes, wavelengths of light, and crystal lattice constants
Common in fields like crystallography, chemistry, and materials science
Though largely replaced by the nanometer in the SI system, the ångström remains widely used in scientific literature to describe very small lengths.
