6.9 Compare and convert units of measure for length, area, weight/mass, and volume within the U.S. Customary system and the metric system and estimate conversions between units in each system: a) length — part of an inch (1/2, 1/4, and 1/8), inches, feet, yards, miles, millimeters, centimeters, meters, and kilometers b) weight/mass — ounces, pounds, tons, grams, and kilograms c) liquid volume — cups, pints, quarts, gallons, milliliters, and liters d) area — square units.

Pg 82 Examples of measurement 6.9 Customary Metric Liter gram centimeter 6.9 Basics pg 83 Capacity - A measure of the ability to receive, hold, or absorb volume. Length - A measure used as a unit to estimate distances. Weight - Weight is determined by the pull of gravity on the mass of an object. The weight of an object changes dependent on the gravitational pull at its location. Mass - Mass is the amount of matter in an object. The mass of an object remains the same regardless of its location. In everyday life, most people are actually interested in determining an object’s mass, although they use the term weight, as shown by the questions: “How much does it weigh?” versus “What is its mass?” Volume –The amount of space that a three dimensional figure contains. Volume is expressed in cubic units, it tells you the number of cubes of a given size are used to fill the figure. Area – The product of the length and the width (A = l  w). The area of a triangle is one half of the measure of the base times the height: A = bh, or A = bh ÷ 2. Square Unit – Units used when measuring the area of a two-dimensional figure.
