Examples: meter, liter, and deka, NOT metre, litre, and deca. Symbols: Symbols for units are never pluralized. The use of informal or non-standard measuring units leads to the need for standard units for better precision and unambiguous communication. A standard unit of measurement is a quantifiable language that helps everyone understand the association of the object with the measurement. The International System of Units (SI) is about measuring the weight or dimensions of objects, not changing their sizes. USC units of measurement for volumes are DIFFERENT for fluids and dry goods: Thus, because compound prefixes are unacceptable, symbols for decimal multiples and submultiples of the unit of mass are formed by attaching SI prefix symbols to g (gram). If you want to add a secondary unit of measure after your primary one, put it in They have crafted five unit plans that will help you to teach measurement and help your class to learn how to measure capacity, volume, area, mass and length using informal units. People need to measure things throughout their lives, including weight, time, length, and many other measureable dimensions.
