Question
Which is equal to 500 milliwatts?
Answer Options
- A) 0.02 watts
- B) 0.5 watts
- C) 5 watts
- D) 50 watts
Correct Answer: B
Explanation
Since ‘milli-’ means one one-thousandth (\text{1/1000}), to convert milliwatts (\text{mW}) to watts (\text{W}), you divide by 1,000.
500\text{ mW} / 1000\text{ mW/W} = 0.5\text{ watts}. Half a watt is a common power level for QRP (low power) portable operation or for handheld transceivers operating on low power settings.
