This digital resource feature profiles for each of the Measurement League: Guardians of the SI superheroes, dedicated to the fight against uncertainty, imprecision, and inaccuracy and to improving the quality of our lives and the things we build. The superheroes include the following: Mole, Professor Second, Monsieur Kilogram, Ms. Ampere, Dr. Kelvin, Meter Man, and Candela. Each card in the set lists a different superhero’s name, picture, symbol, and the measurement unit they represent. The card set provides an entertaining way to learn more about the International System of Units (SI).
