Measurements oflength, height, weight, and volume should be reported in metric units (meter, kilogram, or liter) or their decimal multiples.
Temperatures should be in degrees Celsius. Blood pressures should be in millimeters of mercury, unless other units are specifically required by the journal.
Journals vary in the units they use for reporting hematological, clinical chemistry, and other measurements. Authors must consult the information for authors for the particular journal and should report laboratory information in both the local and International System of Units (SI). Editors may request that the authors before publication add alternative or non-SI units, since SI units are not universally used. Drug concentrations may be reported in either SI or mass units, but the alternative should be provided in parentheses where appropriate.
