Units
SI units and the Celsius scale for temperature should be used, if necessary follow commonly used units can be used: For time - minute (min), hour (h); for volume - cubic decimeter (dm3); For mass - ton (t); for angle measures - degree (o), minute ('), second (''). The negative power should be indicated where necessary, e.g. [cm2 s-1]. Use a space between the numeral and the unit of measure, except with degree, percent, and Svedberg (5oC, 5%, 5S).
