  3. Physicists and other scientists use the International System of Units (SI) in their work because they wish to use a system that is agreed upon by scientists worldwide. Since 2019 the SI units have been defined in terms of fundamental physical constants, which means that scientists anywhere using SI can agree upon the units they use to measure ...

  4. Dec 28, 2020 · A look at the basic scheme of the metric system, also known as the SI system or international system of units, serves to explain why scientists use the metric system for scientific measurements. Its powers of 10 and "crossover" features (e.g., 1 g water = 1 mL water) makes it easy to work with.

  5. The International System of Units, internationally known by the abbreviation SI (from French Système international d'unités), is the modern form of the metric system and the world's most widely used system of measurement.

  7. 4 days ago · International System of Units (SI), international decimal system of weights and measures derived from and extending the metric system of units. SI has seven basic units, from which others are derived: the second, the meter, the kilogram, the ampere, the kelvin, the mole, and the candela.

  8. For centuries, scientists used units of measurement particular to their home countries. This lack of standardization led to many problems. Eventually, scientists agreed to use the International System of Units (SI Units for short!), a standardized system of measurement founded on seven base units.
