Society/association and popular magazines that use SI-metric


Numerous magazines read in the U.S. use metric-system measurements. The magazines listed below are rated according to their use of metric measurements. SI usage falls generally into three categories: 1) SI-metric only; 2) SI-metric followed by inch-pound units in parentheses; and 3) inch-pound units followed by SI-metric in parentheses. When variations occur they are noted. A particular magazine may also contain only a certain percentage of SI-metric usage as noted.
