1. Aim: How do we use metric prefixes?

2. Scientific Notation
When a number is in scientific notation, it is written in the form M x 10n. Let’s write the following numbers in scientific notation: 6,000,000 6, Do you see a general rule?

3. More scientific notation
Now let’s write the following numbers in scientific notation:

4. Metric Prefixes
Prefix Symbol Value Tera T 1012 Giga G 109 Mega M 106 kilo k 103 hecto h 102 deka da 101

5. Metric Prefixes
deci d 10-1 centi c 10-2 milli m 10-3 micro μ 10-6 nano n 10-9 pico p 10-12

6. Base Units Meters = m Seconds = s Grams = g
When we place a metric prefix in front of these units, we change the meaning of the unit.

7. Examples: Applying Metric Prefixes
We will practice applying metric prefixes to the meter. Write the name for the following: 1. Tm 2. km 3. pm 4. hm

8. Examples: Applying Metric Prefixes
We will practice applying metric prefixes to the second. Write the symbol and value of each unit: 5. nanosecond 6. dekasecond 7. millisecond 8. Megasecond

9. Metric Facts
1 Tm = ___m 1s = __ns 1 km = __m 1 s = __das 1m = __pm 1s = __ms 1 hm = __m
