Inchworm

Have you ever found a tasty-sounding recipe from England or another country that uses the metric system and wasn’t sure how to make the conversions? Get a handy chart, as well as some metric-measured recipes, from the National Institute of Standards and Technology .

An inch is an inch, but do you know how many millimeters it is? In every day life, we measure in inches, pounds, or pints. But most countries use what is called the metric system. Scientists in the U.S. and other countries use the metric system, too.

The International System of Units (SI), commonly known as the metric system, is the international standard for measurement. Even if we are more familiar with inches, feet, and yards, students need to be comfortable with metric measurements to move forward in science and many other fields. The National Institute of Standards and Technology has collected resources to enrich your curriculum and reinforce student learning on the metric system .

First Version

Written by Frank Loesser | Featured in the biographical movie "Hans Christian Andersen."

Inch worm, inch worm
Measuring the marigolds
Could it be, stop and see
How beautiful they are

Chorus

Two and two are four
Four and four are eight
Eight and eight are sixteen
Sixteen and sixteen are thirty-two

Inchworm, inchworm
Measuring the marigolds
You and your arithmetic
You'll probably go far

(Repeat Chorus)

Inchworm, inchworm
Measuring the marigolds
Seems to me you'd stop and see
How beautiful they are

Another Version

Lyrics by Mark Rew

Stay, longer, for me,
Wait, longer, for me,
I know you must be getting sick,
of wondering exactly where this leads you,
Why did it take so long,
why did it take so long,
Why did it take so long,
Stay, longer, for me,
Wait, longer, for me,
I know you must be getting sick,
of wondering exactly where this leads you,
Why did it take so long,
Why did it take so long,
Why did it take so long,
Inchworm, inchworm,
measuring, the merrygold.
