o Temperature degrees on the Fahrenheit or Celsius scale

o Time seconds, minutes, hours, days, weeks, months, years

TYPES OF MEASUREMENTS

Measuring With MaggieAn Introduction to US Standard Units

Also known as “Imperial Units" or "US Customary Units"

Wow, I just flew in from planet Micron. It was a long flight, but well worth it to get to spend time with you!My name is Maggie in your language (but you couldn't pronounce my real name!)

When I first arrived I couldn't understand how you measure things, but my friend Tom taught me all about measurement, and I am going to share with you everything he taught me.

The first thing Tom told me was that you can measure things using two different systems: US Standard Units and Metric.Today is my day to learn US Standard Units !

Fluid Ounces Cups Pints Quarts Gallons

Liquids

The first thing I need to know when asking for a drink is the types of units used to measure liquids, which are:

Fluid Ounces (oz) are small. About how much would fit into a small medicine cup ... but that wouldn't be enough for someone who is thirsty!

Then Tom showed me a small carton, and told me it held 8 ounces, which is also called 1 cup. But I wanted more!

So Tom showed me a pint, which is equal to 2 cups.That seemed about right for someone who was very thirsty!

(Tom also told me that I can measure things using measuring cups)

If you were measuring many cups of liquid all put together, you might have to use quarts.A quart (qt) is the same thing as 4 cups or 2 pints.

If you still need more liquid you may want to switch to using gallons.A gallon (gal) is the same as 16 cups or 8 pints or 4 quarts. It is the largest liquid measurement.

So now I know that 1 ounce is too small for me, but 1 gallon would be too much. I think I will ask for a pint of juice!

Final thoughts about measuring liquids:

1 Gallon = 4 quarts = 8 pints = 16 cups= 128 fluid ounces

Mass (Weight)

Ounces Pounds Tons

Next I wanted to eat some chocolate ... so I should learn about mass. You often call it "weight", but it is only because of the gravity on your planet that items have weight! Tom says I need to know:

Ounces Again!One thing that really confused me is that when I asked for a drink I could use ounces, but ounces are also used for mass ...... the same word can be used in two different measuring systems! How amazing is that? But they are really different.

The smallest unit of mass is ounces (oz). A slice of bread is about one ounce. It is very light.

If you have 16 ounces, it can also be called a pound (lb). Typically, this is the unit that you use to measure your own weight. 1 pound = 16 ouncesPounds are used to measure lots of things from people to food to animals.

2,000 pounds is also one ton. 1 ton = 2,000 poundsThat is really heavy! Trucks, ships and heavy equipment are measured using tons instead of pounds.An elephant has a mass of about 8 tons!

So now I know that 1 ounce of chocolate is too small for me, but 1 ton would be too

much. I think I will ask for a pound of chocolate!

Final thoughts about mass:1 pound = 16 ounces

1 Ton = 2,000 pounds = 32,000 ounces

Length

The last kind of measurement we are going to explore is length. This is important for lots of different reasons. Measurement of length helps you to know how far you have traveled, how far you have left to travel, how tall you are and many other things.

Inches Feet Yards Miles

Lots of things are measured in inches from rainfall to paper length. Measuring in inches provide us with a way for everyone to understand the size of something.

Small units of length are called inches.

The last joint of your finger or thumb is about 1 inch (depending on how big your fingers are!).

Lots of things are measured in inches from rainfall to paper length. Measuring in inches provide us with a way for everyone to understand the size of something.

When you have 12 inches together, it is known as a foot. 1 foot = 12 inchesA long time ago, people had to use their own feet to measure things. However, since everyone has different sized feet, it did not let everyone understand the size or distance in the same way.

Using 12 inches put together to make feet allows for everyone to have a more accurate picture of what exactly a "foot" of length is.

When 3 feet are together, this is called a yard. (This isn’t the same thing as a lawn, though they are both referred to as a "yard"!)

1 yard = 3 feetThe length of this guitar is about 1 yard.

When you put together 1,760 yards, you have a mile. 1 mile = 1,760 yards = 5,280 feetMiles are long distances and are mostly used to measure the distance between places which are far away from each other. Most people refer to miles when they are driving, biking or jogging.

Final thoughts about measuring length:

1 foot = 12 inches1 yard = 3 feet = 36 inches

1 mile = 1,760 yards = 5,280 feet = 63,360 inches

Temperature

I was feeling a bit hot, so I asked Tom how to measure temperature.So he showed me a thermometer. But I saw 2 sets of numbers!Tom explained that a thermometer measures in degrees (°) of either Celsius or Fahrenheit. "Why two scales?", I asked. Tom said that some people like one scale and some like the other, and that I should learn both!He than gave me an example: when water freezes the thermometer shows:0 degrees Celsius on the left side, but on the right side it shows 32 degrees Fahrenheit.Two numbers for the same thing!

He gave me more examples.•A hot sunny day might have a temperature of 30 degrees Celsius but would be 86 degrees in Fahrenheit. •Water boils at 100 degrees Celsius or 212 degrees Fahrenheit. •And you can bake cookies in your oven at a temperature of 180 degrees Celsius, but that would be 356 degrees Fahrenheit.

1 second is about as long as it takes to say "one thousand and one“

1 Minute is equal to sixty seconds.

TIME

There are 60 minutes in an HourAn hour is 60 minutes, and a minute is 60 seconds, so an hour is:60 × 60 = 3,600 secondsDayA day is 24 hours so:1 day = 24 × 60 × 60 = 86,400 secondWeekA week is seven daysMonthA month is 28 days (29 leap year30 days or 31 daysYearThere are 365 days in a year, except leap year with 366 days.

WE WILL NOW VIEW A VIDEO

ON MEASUREMENT FROMNASA

m the meter for length

kg the kilogram for mass

s the second for time

Metric System of Measurement(Correctly called "SI")

The metric system is a s system of measuring. It has three basic units:

With those three simple measurements we can measure nearly everything in the world!

Meter

Kilogram

This gold bar has amass of 1 kilogram.

A dictionary has a mass of about 1 kilogram

Larger or SmallerBut what if we want to talk about really big or really small things?Answer: we can use Metric Number Prefixeslike "kilo" (a thousand) and "milli" (one thousandth) and so onExample: something that is 1,000 meters is a "kilometer"Something that is one thousandth of a second is a "millisecond"In fact the kilogram already uses this method, because it is a thousand grams, a kilogram.

WHAT WE HAVE LEARNED

• There are two systems of measurement we need to know, Imperial and Matric• Each system uses certain vocabulary and tools to complete

accurate measurements• Different units are used to measure linear, time, weight,

mass, and temperature• Each of the measurement units can be converted to other units in the same category, example, inches to feet to miles.• The Metric system is a “Base Ten” system using meters,

liters and grams as its main categories for measuring.
