To convert units in the metric system, identify the unit that you have, the unit that you want to convert to, and then count the number of units between them.
| Prefix | Symbol | Decimal Equivalent | Pronounced | Exponential Expression |
|---|---|---|---|---|
| tera- | T | 1,000,000,000,000 | TER-uh | 1012 |
| giga- | G | 1,000,000,000 | GIG-uh | 109 |
| mega- | M | 1,000,000 | MEG-uh | 106 |
| kilo- | k | 1,000 | KIL-oh | 103 |
| hecto- | h | 100 | HEK-toe | 102 |
| deka- | da | 10 | DEK-uh | 10 |
| deci- | d | 0.1 | DES-ee | 10-1 |
| centi- | c | 0.01 | SEN-tee | 10-2 |
| milli- | m | 0.001 | MIL-ee | 10-3 |
| micro- | µ | 0.000,001 | MY-kro | 10-6 |
| nano- | n | 0.000,000,001 | NAN-oh | 10-9 |

You can use the following sentence to remember the prefixes in order:
King Henry Doesn't [Usually] Drink Chocolate Milk
The first letters of the words stand for the prefixes, with "Usually" in the middle standing for the "unit" being converted:
kilo- hecto- deka- [unit] deci- centi- milli-
Use this form to convert electrical units for test results, for example:
- teraohms to gigaohms
- teraohms to megaohms
- teraohms to kiloohms
- teraohms to ohms
- gigaohms to megaohms
- gigaohms to kiloohms
- gigaohms to ohms
- megaohms to kiloohms
- megaohms to ohms
- megaohms to gigaohms
- megaohms to teraohms
- ohms to microhms
- ohms to milliohms
- microhms to milliohms
- millivolts to volts
- kilovolts to volts
- amps to milliamps
