  2. Angstrom - Wikipedia

    en.wikipedia.org/wiki/Angstrom

    It was only in 1960, when the metre was redefined in the same way, that the angstrom became again equal to 10 −10 metre. Yet the angstrom was never part of the SI system of units, [13] [14] and has been increasingly replaced by the nanometre (10 −9 m) or picometre (10 −12 m).

  3. Orders of magnitude (length) - Wikipedia

    The decimetre (SI symbol: dm) is a unit of length in the metric system equal to 10 −1 metres (⁠ 1 / 10 ⁠ m = 0.1 m). To help compare different orders of magnitude , this section lists lengths between 10 centimeters and 100 centimeters (10 −1 meter and 1 meter).

    The solar flux unit is a unit of spectral irradiance equal to 10 −22 W⋅m −2 ⋅Hz −1 (100 yW⋅m −2 ⋅Hz −1). The nox (nx) is a unit of illuminance equal to 1 millilux (1 mlx). The nit (nt) is a unit of luminance equal to one candela per metre squared (1 cd⋅m −2). The lambert (L) is a unit of luminance equal to 10 4 /π cd⋅m ...
