LECTURE 3.2 – CONVERSION FACTORS

Today’s Learning Targets LT 3.3 – I can discuss how to convert between two related units and explain how to complete a multi – step conversion problem involving unrelated units.

How do we convert between units?

I. Conversion Factors To convert between two different units we use a conversion factor. A conversion factor allows you to convert between units.

I. Conversion Factors Units You Want Units You Have Number that you have Number with New Units

Conversion Factors Example – Convert $15 to cents 100Cents 1 Dollars 15 Dollars 1500 ¢

Table Talk Convert 250 cm to inches (Note – 1 in = 2.54 cm)

II. Multi-Step Conversions Often times, we need to take multiple steps to convert between units. We must set up a series of conversion factors so that all unnecessary units cancel one

Convert 3 hours to seconds 1 hour 3 hours 10,800 sec 60 min 1 min 60 sec

Table Talk How many days are there in 525,000 seconds? (Note – 1 day = 24 h, 1 h = 60 min, and 1 min = 60 s)

White Board Races

Question 1 Convert 500 minutes into seconds

Question 2 You have 5 dozen doughnuts, how many doughnuts do you have (12 doughnuts = 1 dozen)

Question 3 You have 14 cups of water, how many gallons of water do you have (1 gallon = 4 quarts; 1 quart = 4 cups)

Question 4 You have 32 cups of solution. How many gallons do you have? (1 gallon = 4 quarts; 1 quart = 4 cups)

Question 5 How many minutes are there in 1 year?

Mr. Astor World Traveler Stations Please follow the instructions on the handout and travel to each station accordingly.

USA  South Africa  Zambia Finish the Journey to at least Zambia before the bells rings.

Wanna Travel the World? If the whole class finishes the required stations, Mr. Astor will show you the rest of the pictures.
