1.1 Imperial Measurements MFM2P

I need a bolt as wide as thumb In the beginning Back in the day (1000s of years ago) when people built things themselves, it wasn’t necessary to measure things because everyone did it themselves. I need a bolt as wide as thumb

What you talkin’ ‘bout Willis? However, projects became more complicated, it became necessary to have others work different parts, therefore they had to standardize measurement. moron… Sir, I don’t know what your thumb looks like…

An inch was the width of a thumb Birth of Imperialism So they decide to take the most popular guy, measure his thumb and call it an inch. This guy was the King! An inch was the width of a thumb A foot was the size of the kings foot, which eventually became 12 inches. A yard was the distance from the tip of a man's nose to the end of his outstretched arm. Eventually, 3 feet became a yard

Other systems The British empire used this method to devise measurements for mass, volume and time. For instance a pound was equal to 7002 troy grains Other countries developed their own units of measure 7001? That’s stupid! A pound should be 7002… Your sands are no match for our stones! What’s a troy grain? We use wheat seeds

A new day Eventually (in the 1800s), the French developed the Metric System In the 1970s many commonwealth (former British colonies) switched to the metric system.

Imperial Systems Today, the entire world is metric, except for the US, Myanmar and Liberia

The Imperial Empire Unfortunately, the US has a HUGE influence on our culture. This influences the way we communicate and think about various systems of measurement. Time is in seconds, minutes, hours, days,etc… How tall are you?  5 feet 10 inches How much do you weight?  210 lb Football field  yards Fluids (Guinness)  pint

inches (in or “), foot (ft or ‘), yard (yd), mile (mi) Going the distance… Length inches (in or “), foot (ft or ‘), yard (yd), mile (mi)

Pump up the Volume! Volume Teaspoon (tsp), tablespoon (tbsp), fluid ounce (fl oz), cup (c), pint (pt), quart (qt), gallon (gal)

Ounce (oz), pound (lb), ton (tn) Weight Weight Ounce (oz), pound (lb), ton (tn)

Miscellaneous

Imperial Units Length Volume Weight inches (in or “), foot (ft or ‘), yard (yd), mile (mi) Volume Teaspoon (tsp), tablespoon (tbsp), fluid ounce (fl oz), cup (c), pint (pt), quart (qt), gallon (gal) Weight Ounce (oz), pound (lb), ton (tn)

If 1 yd = 3ft, then 4 yd2 = ft2 4 yd2 36 ft2 1 yd 3ft 2 yd 6 ft 2 yd

Converting Feet to Inches Page 3 Question 3 Converting Feet to Inches 1 foot = 12 inches 8.5’ = 8.5 feet 2’ 7” = 2‘ + 7” 3’ = 3 feet = 8.5 x 12” = (2 x 12”) + 7” = 3 feet x 12 inches 1 foot = 36” = 102” = 24” +7” = 31”

Converting Inches to Feet Page 3 Question 4a Converting Inches to Feet 1 foot = 12 inches 71 inches = How many times does 12 go into 71? 71 inches = 5 feet + ??? inches 71 inches = 5 feet + 11 inches 5’ = 60” 71” -60” = 11”

Word Problems = (220 ft) (180 ft) Page 3 Question 6 Word Problems The school gymnasium floor needs to be resurfaced. Hardwood flooring costs $6 per square foot plus $2.50 per square foot for installation. The gym measures 180ft by 220ft. a) Size of gym = (length) (width) = (220 ft) (180 ft) = 39 600ft2 Therefore the gym is 39 600ft2. b) Cost to buy hardwood = ($6.00/ft2) (39 600ft2) = $237 600 The cost of the hardwood is $237 600. c) Cost of Installation = ($2.50/ft2) (39 600ft2) = $99 000 Therefore the cost of installation is $99 000
