Answer Notes

In electronics, metric prefixes denote specific powers of ten. 'Micro-' means one millionth (10^-6), while 'pico-' means one trillionth (10^-12). The difference between micro and pico is a factor of one million (1,000,000). Therefore, moving from a smaller unit (picofarads) to a larger unit (microfarads) requires dividing the value by 1,000,000. Dividing 1,000,000 picofarads by 1,000,000 gives exactly 1 microfarad. The distractors result from miscounting the required decimal point shifts.
