EnglischOhm (Ω) is the SI unit of electrical resistance, named after Georg Ohm, a German physicist. An ohm is defined as the resistance between two points of a conductive medium when 1V (Volt), applied to these points, produces a current of 1A (Ampere). Electrical resistance is measured in SI units and can range from microohm to teraohm, being able to calculate these values in terms of Ohms is key to any electrical equation including resistance calculations.
These values are displayed as:
| Prefix | Name | Meaning |
|---|---|---|
| µΩ | Microohm | One microohm is equal to 1/1,000,000 (10-6) of an ohm |
| mΩ | Milliohm | One milliohm is equal to 1/1,000 (10-3) of an ohm |
| Ω | Ohm | One ohm is the baseline for all other SI unit conversions |
| kΩ | Kiloohm | One kiloohm is equal to 1,000 (103) ohms |
| MΩ | Megaohm | One megaohm is equal to 1,000,000 (106) ohms |
| GΩ | Gigaohm | One gigaohm is equal to 1,000,000,000 (109) ohms |
| TΩ | Teraohm | One Teraohm is equal to 1,000,000,000,000 (1012) ohms |
