The term 'micron' was officially accepted alongside 'micrometre' but was deprecated by the SI in 1967 in favour of 'micrometre' (μm). However, it remains in widespread use in many technical fields.

A micron (micrometre) is one millionth of a metre (10^-6 m). A nanometre is one billionth of a metre (10^-9 m). There are 1000 nanometres in one micron.

Yes, the standard plural is 'microns' (e.g., 'The particles range from 1 to 10 microns in size').

No, the standard English spelling is 'micron'. 'Mikron' is a non-standard spelling, sometimes seen as a transliteration from other languages or a brand name, but it is not correct for the unit of measurement.

A unit of length equal to one millionth of a metre (1 μm).
