Si

(Verse 1)

In the lab or out in space,

We need a way to find the place.

Standard measures, world-wide rules,

The SI system is the king of tools.

Forget the inches, forget the feet,

These seven units make the world complete!

(Chorus)

Oh, there are seven base units we use every day,

To measure the world in a scientific way.

From the heat of a star to the tick of a clock,

The SI system is our solid rock!

(Verse 2 - The Big Three)

First, there’s Length, it’s a distance race,

The Meter (m) keeps the steady pace.

Then there’s Mass, what’s inside the thing?

The Kilogram (kg) is the heavy king.

And for the Time that’s passing by,

The Second (s) is the unit we apply.

(Verse 3 - The Invisible Forces)

Flowing current, a steady stream,

The Ampere (A) powers up the dream.

How hot is the fire? How cold is the ice?

The Kelvin (K) measures temperature precise.

How much substance? How many bits?

The Mole (mol) is the unit that fits.

(Bridge)

Wait! There’s one more, don’t you see?

To measure the light for you and me.

How bright does that candle glow?

The Candela (cd) lets you know!

(Chorus)

Oh, there are seven base units we use every day,

To measure the world in a scientific way.

From the heat of a star to the tick of a clock,

The SI system is our solid rock!

(Outro)

Meter, Kilogram, Second, and Ampere,

Kelvin, Mole, and Candela are here.

Seven units, one big plan...

Measure the universe because we can!
