The Metric System
SI (System International)
Metric System•Used by every country in the
world, except the USA.
•Always used by scientists.
•Based on the number 10, so it’s easy!
Measuring Length
•Length= the distance between 2 points.
•Base unit= meter (m)
•Use rulers and meter sticks to measure
Problems: We need more accuracy
o We can’t measure everything with just base units
o We need prefixes!
Metric Units

We will be using graduated cylinders to find the volume of liquids and other objects.
Read the measurement based on the bottom of the meniscus or curve. When using a real cylinder, make sure you are eye-level with the level of the water.
What is the volume of water in the cylinder? _____mL
