A millimeter, you can understand
Is about as long as a grain of sand
When you buy food at lunchtime
It's about the thickness of a dime
A staple from side to side
Is about a centimeter wide
A fingernail on a girl or guy
Is about a centimeter high
Ten millimeters, a centimeter
A hundred centimeters, is a meter
A thousand meters, that's a kilometer
And it's the same for grams and liters
A school bus wheel's diameter
Is about one meter
And a meter is about as far
As the length of a guitar
Ten soccer fields in a row
About a kilometer you'll go
It's about how far you'd walk
If you crossed twelve city blocks
Ten millimeters, a centimeter
A hundred centimeters, is a meter
A thousand meters, that's a kilometer
And it's the same for grams and liters
Imagine holding a grain of sand
About a millimeter
Or a marble in your hand
About a centimeter
Your hand is from the floor
About a meter
A ten minute walk on the shore
About a kilometer
Ten millimeters, a centimeter
A hundred centimeters, is a meter
A thousand meters, that's a kilometer
And it's the same for grams and liters
Ten millimeters, a centimeter
A hundred centimeters, is a meter
A thousand meters, that's a kilometer
And it's the same for grams and liters
