The watt (symbol: W) is a derived unit of power in the International System of Units (SI) defined as 1 joule per second and can be used to quantify the rate of energy transfer. Power has dimensions of ML2T-3.
| 1 watts = 1000 milliwatts | 6 watts = 6000 milliwatts |
| 2 watts = 2000 milliwatts | 7 watts = 7000 milliwatts |
| 3 watts = 3000 milliwatts | 8 watts = 8000 milliwatts |
| 4 watts = 4000 milliwatts | 9 watts = 9000 milliwatts |
| 5 watts = 5000 milliwatts | 10 watts = 10000 milliwatts |
The milliwatt (mW) is equal to one thousandth (10−3) of a watt. A typical laser pointer outputs about five milliwatts of light power, whereas a typical hearing aid for people uses less than one milliwatt. Audio signals and other electronic signal levels are often measured in dBm, referenced to one milliwatt.
| 1 milliwatts = 0.001 watts | 6 milliwatts = 0.006 watts |
| 2 milliwatts = 0.002 watts | 7 milliwatts = 0.007 watts |
| 3 milliwatts = 0.003 watts | 8 milliwatts = 0.008 watts |
| 4 milliwatts = 0.004 watts | 9 milliwatts = 0.009 watts |
| 5 milliwatts = 0.005 watts | 10 milliwatts = 0.01 watts |
| 1 watts = 1 000 milliwatts |
| 1 milliwatts = 0.001 watts |
