Metric Notes Metric System- Scientific System of Measurement
BASIC UNITS OF THE METRIC SYSTEM • The meter (m) is the base unit of length. • The gram (g) is the base unit of mass. • The liter (L) is the base unit of volume.
Prefixes Prefix Symbol Meaning in words Meaning in Kilo k Thousand numbers 1, 000 Hecto h Hundreds 100 Deka da Tens 10 Deci d Tenths . 1 Centi c Hundredths . 01 Milli m Thousandths . 001
Converting Units To convert from one unit to another is like following directions on a map. Which way? Left or Right?
Going Left? ? ? When going from a smaller unit to a larger unit, you move Left on the map and the decimal moves to the LEFT. However, the actual number decreases.
Going Right? ? ? When going from a larger unit to a smaller unit, you move RIGHT on the map and the decimal moves to the RIGHT. However, the actual number increases.
Let’s take a look!!!
King Henry Died By Kilo Hecto Deka Basic Unit Liters Meters Grams Drinking Chocolate Milk Deci Centi Milli
Practice Time 4. 5 m = ? cm
What to do first in the problem 4. 5 m = __ cm ? Start at Meters and move to the Right to Centimeters. Decimal place moves to the RIGHT two spaces. Kilo Hecto Deka 4. 5 Basic Unit . Deci . Centi . Milli
As you move the decimal you will need to add zeros. 4. 5 0.
Is this your Final Answer? 4. 5 m = 450 cm
Let’s do another one! 6. 6 liters = _____ m. L
What to do first in the problem 6. 6 L = __ m. L ? Start at Liters and move to the Right to Millileters. Decimal place moves to the RIGHT three spaces. Kilo Hecto Deka 6. 6 Basic Unit . Deci . Centi . Milli .
Check your answer! 6. 6 liters = 6, 600 m. L
Let’s Go the Other Way! 3, 580 mm = _______ m?
Let’s move to the left this time. 3, 580 mm = ______m? Start at Millimeters and move to the Left to Meters. Decimal place moves to the LEFT three spaces. Kilo Hecto Deka Basic Unit 3580 . Deci . Centi . Milli .
Check your answer: 3, 580 mm = 3. 58 m
Quiz Time 1. 2. 3. 4. 5. 28 cm = ? mm 438 cm = ? m 72 g = ? mg 202 g = ? kg 2 L = ? m. L
How did We do? ? 1. 2. 3. 4. 5. 28 cm = 438 cm = 72 g = 202 g = 2 L = 280 mm 4. 38 m 72, 000 mg 0. 202 kg 2, 000 m. L
