This deck contains all twenty of the IS unit prefixes ranging from yocto (10^-24) to yotta (10^24). For each prefix, there are three cards:
1. Multiplier from prefix.
2. Abbreviation from prefix.
3. Prefix from multiplier.
This deck was inspired by the shared deck here:
https://ankiweb.net/shared/info/635426598. In this deck, however, I changed the formatting to make it more immediately clear what each card is asking. For example, for cards asking for the multiplier, only the exponent is occluded, so it is clear that the card is asking for a number.
