A Lesson in Measurement

Student Packet

For HOW BIG? A Lesson in Measurement Vocabulary List

Volume = measure of the interior of a three dimensional figure. Expressed in cubic units. Mass = the amount of matter in an object. Expressed in pounds and kilograms. Length = a number that tells how many units there are in a segment. Expressed in linear units. Graduate container = container with lines for liquid measurement. Radius = the distance from the center of a circle to any point on that circle. Diameter = a line segment with endpoints on the circle that passed through the center of the circle (2 times the radius) Circumference = the distance around a circle Estimate = an educated guess Extrapolate = predicting values outside the given facts of the graph Interpolate = predicting values between two points on a graph Conversion = changing Metric to English units or visa versa Scale = instrument used to weigh objects

VOLUME ENGLISH METRIC Gallon Gal Liter L Quart Qt Milliliter Ml Pint Pt Centiliter Cl Cup C Ounce Oz EQUIVALENT 1gal = 4qt 1 L = 1000 ml (cc) 1qt = 2 pt 1L= 100cl 1 pt = 2 C 1cl = 10ml 1 C = 8 oz 1 oz = 2 Tbsp 1 Tbsp = 3 tsp VOLUME CONVERSION 1 oz = 30 ml = 30 cc

LENGTH Mile mi Kilometer Km Yard yd Meter M Feet ft Centimeter Cm Inches in Millimeter Mm EQUIVALENT 1 yd = 3ft 1 km = 1000 m 1 ft = 12 in 1 m = 100 cm 1 cm = 10 mm LENGTH CONVERSION 1 in = 2.54 cm 1 mi = 1.6 km

MASS Pound lb Kilogram Kg Ounce oz Gram Gm Milligram Mg EQUIVALENTS 1 lb = 16 oz 1 kg = 1000 g 1 gm = 1000 mg MASS CONVERSIONS 2.2 lb = 1 kg 1oz = 28 g

FORMULAS Volume of rectangular solid: l x w x h = v Volume of a cylinder: π x r 2 x h = v Area of a Triangle = ½ b h

Neat Fact:

2 In the Metric system, the three types of measurement are related. If you made a cube that measured one centimeter and filled it with water, the amount it would hold is one milliliter. Then, if you massed that cube of water, it would equal one gram.

1cc = 1ml = 1g cl = centiliter
