  2. International roughness index - Wikipedia

    en.wikipedia.org/wiki/International_roughness_index

    It is calculated using a quarter-car vehicle math model, whose response is accumulated to yield a roughness index with units of slope (in/mi, m/km, etc.). [ 1 ] [ 2 ] Although a universal term, IRI is calculated per wheelpath, but can be expanded to a Mean Roughness Index (MRI) when both wheelpath profiles are collected.

  3. Orders of magnitude (length) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(length)

    The megametre (SI symbol: Mm) is a unit of length in the metric system equal to 1 000 000 meters (10 6 m). To help compare different orders of magnitude, this section lists lengths starting at 10 6 m (1 Mm or 1,000 km).

  9. Conversion of units - Wikipedia

    en.wikipedia.org/wiki/Conversion_of_units

    The factor–label method can convert only unit quantities for which the units are in a linear relationship intersecting at 0 (ratio scale in Stevens's typology). Most conversions fit this paradigm. An example for which it cannot be used is the conversion between the Celsius scale and the Kelvin scale (or the Fahrenheit scale). Between degrees ...
