Q. What is the metric system?
A. The metric system is a decimal-based system of measurement units. Units for a given quantity, such as length or mass, are related by factors of 10. Calculations involve the simple process of moving the decimal point to the right or to the left. This modem system is called Le Système International d'Unites or the International System of Units, abbreviated SI.
Q. Is the metric system hard to learn and use?
A. No. In everyday usage, the most common metric units are the meter (m) to measure length, the second (s) to measure time, the kilogram (kg) for mass (or weight*), the liter (L) for volume, and the degree Celsius (°C) for temperature. The metric system avoids confusing dual-use of terms, such as the inch-pound system's use of ounces to measure both weight and volume. The metric system also avoids the use of multiple units for the same quantity; for instance, the inch-pound system's multiple units for volume include teaspoons, tablespoons, fluid ounces, cups, pints, quarts, and gallons.
