Lesson # 18
Metric Conversions
MASS !
Yes…Mass
And
It has nothing to do with church.
However, you may need help From
GodIf you do not
Pay Attention !
MassIt’s the thing often referred to as weight.
Like…
A loaf of bread has a mass of 645 grams
Or
“You” might have a mass of 80 kg
Like your fit and trim
Math teacher !
He is so trim…
He tilts the scale at a whopping80 kg.That’s
175 pounds.
(Mostly muscle)
So what then is a kg?
A kg is one thousand
G’s.
So what is a G?
It’s a gram.
And a gram is
1000 times greater
thana
mg.
A gram is…
About the mass of a blueberry!
1000 of them
Make
1 Kilogram !
And
A lot of muffins.
And an “mg” is…
A milligram !
They are really small.
Doctors usually measure pills in Milligrams.
One pill would be close to 100 mg.
To summarize…
1 kg = 1000 grams
1000 mg = 1 gram
Sooooo…
1 000 000 mg = 1 kg
Got it?
Good.
Now let’s look at the conversion.
It is very similar to
Other metric conversions.
First…
Decide if you are converting…
Bigger to smallerOr
Smaller to bigger.
Once you decide…
If converting bigger to smaller…
Multiply !X
If converting…
Smaller to bigger
Divide
÷
Don’t forget…
1000 mg = 1 g
1000 g = 1 kg
1 000 000 mg = 1 kg
Here is an example…
3.2 g = ? Mg
3.2 X 1000 =
3200 mg
The decimal moved 3 places.
Another example…
5.67 kg = ? Mg
5.67 X 1 000 000 =
5 670 000 mgThe decimal moved 6 places !
And now…
