**Metric Prefixes** are “labels” that can be placed in front of base units.

Concept #1: Understanding Metric Prefixes

**Transcript**

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

**Transcript**

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.

Part B. The conversion factor relating feet to meters is 1 ft = 0.305 m. Keep in mind that when using conversion factors, you want to make sure that like units cancel leaving you with the units you need.You have been told that a certain house is 164 m2 in area. How much is this in square feet?Keeping track of units during conversions can get confusing. Therefore, a good strategy is to use dimensional analysis. In dimensional analysis, conversion factors are used to cancel out unwanted units and leave the desired units.Consider the following example: How many football fields could fit on a 1 mile stretch of land? Here are the relevant conversion factors:1 football field = 100 yards1 mile = 5280 ft1 yard = 3 ftThen1 mile×5280 ft1 mil3×1 yard3 ft×1 football field100 yard=17.6 football fields
