Metric Conversions

In Science, the most commonly used system of measurement is the metric system. No matter where you are in the world, you are more likely to see metrics used than the standard system of inches, miles, pounds, and ounces we use here in the United States.

Metric Mass:

Mass is measured in Grams.

Typically, we use a balance in the science classroom to measure mass.

To read the balance, you need to look at the three "beams".

According to the measurement, the hundreds is on 300g, the tens is on 50g, and the ones is on 4.6g. Add these three numbers up and you have 354.6g

Metric Distance:

Distance is measured in Meters.

Typically we use a ruler, or a trundle wheel (depending on the length of distance).

Metric Volume:

Metric volume can be either a liquid or a solid.

Liquid volume is measured in liters.

Solid volume is measured in meters (cubed)

We use a graduated cylinder for liquid.

Measuring the volume of a solid, you measure the length, the width, and the height of the object with a ruler.

Plug the numbers into this formula:

Length x Width x Height

Volume = 5cm x 2cm x 3cm

V = 30 cm(3)
