Metric Prefixes are “labels” that can be placed in front of base units.
Concept #1: Understanding Metric Prefixes
Now, what exactly is a metric prefix? Just understand it's kind of like a label that goes in front of what we call base units.
Now, what's a base unit? Good examples of base units are liters or seconds or grams or moles or minutes, these can be understood as base units and all a metric prefix is is a label that goes in front of that base unit, to describe what kind of base unit we're dealing with.
Here we're going to say we could have deciliters or kiloseconds or nanograms or millimoles or microminutes. The metric prefix is just a way of describing a change that's going on with that base unit, so they're just labels that go in front.
Concept #2: Using the Metric Prefix Chart
If we take a look here at this chart, this gives us a majority of the metric prefix that you're responsible for. Now there are some that go after pico and there are some that go after tera, but for the most part, professors will stick to this core group of metric prefixes.
What we're going to have to say here is, just remember, this is very important, one—is associated with the metric prefix, so one is associated with each one of this metric prefixes. What does that mean?
Let's say I had a picometer. Meter is the base. Pico is the metric prefix that goes in front of it. Since one is associated with my metric prefix, we're going to say 1 picometer is equal to, see right here, 10-12 meters. It's a way of setting things where you form a relationship between the metric prefix and the base.
Let's say I had kilo. So let's say I had kilograms and I wanted to go to grams, so we'd say that for every 1, because kilo is a metric prefix for every 1 kg, it is 103 grams, so that's what I mean by 1 is associated with the metric prefix. So remember that when we're doing these types of metric prefix conversions.
Whenever using the metric prefix chart, remember that “1” is associated with the metric prefix.
