What is the ratio of angstrom and femto-metre?

CONCEPT:

• Angstrom: The unit of length which is equal to 10−10 meters is called one Angstrom.
  • Angstrom is denoted by Å.

​⇒ 1 Å = 10-10 m

• Fermi: It is a small practical unit of distance used for measuring nuclear size. It is also known as a femtometer. A femtometer is denoted by fm.

⇒ 1 fermi = 1 fm = 10^-15 m

CALCULATION:

• Ratio of (1 angstrom / 1 femtometer).

\( ⇒ \frac{{{{10}^{ - 10}}}}{{{{10}^{ - 15}}}} = {10^{\left( { - 10} \right) - \left( { - 15} \right)}} = {10^5}\)
