aquakin.parse_units#

aquakin.parse_units(text)[source]#

Parse a unit string into a Dimension, or None if unknown.

Parameters:: text (str) – A unit string in any of the shipped dialects, e.g. "g_COD/m3", "1/d", "M-1 s-1", "m3/(g_COD*d)", "gO2^0.5/m/d", "mol/L". The display form is accepted too: Unicode superscripts (m³) and the multiplication dot (g_COD·m⁻³ == g_COD*m-3).
Returns:: The parsed dimension. "-" (or "1") is the dimensionless Dimension(). A blank string, or any string this tolerant parser cannot fully consume, returns None (treated as unknown / skipped by the check) rather than raising.
Return type:: Dimension or None
