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 !
