### Q: What are the common prefixes used in the metric system?

The most common prefixes used in the metric system are kilo, mega, giga, tera, and pico, representing various magnitudes of measurement.

## Summary & Key Takeaways

• The metric system uses prefixes to represent different magnitudes, with deca (10), hecto (100), kilo (1,000), mega (1,000,000), and giga (1,000,000,000) being commonly used.

• Conversion factors are written by attaching a 1 to the prefix and the multiplier to the base unit, such as meters or liters.

• Conversion between units is done by canceling out the unwanted unit and using the appropriate conversion factors.
