Turn your physics notes into prefix flashcards with AI
Printed prefix charts are fine for a quick glance, but they don't match your course. Upload your lecture slides, notes, or a photo of your textbook page and DeckOwl builds flashcards from your own material, with spaced repetition to keep the prefixes in memory.
Why generate your own prefix cards
Most printable prefix sheets list nano, micro, and mega without showing how your course uses them, so you end up memorizing a table that doesn't match your problem sets. Generating physics prefixes flashcards from your own material keeps the cards tied to the units and examples in your class.
- Pull prefixes from your own lecture slides or textbook pages
- Test both directions: symbol to meaning and meaning to power of ten
- Review hard cards more often with built-in spaced repetition
- Export to Anki or CSV on the Plus plan when you want cards elsewhere
Built from your material
Upload PDFs, PPTX slides, DOCX files, plain notes, or photos of pages. Prefixes are pulled from the wording your instructor actually uses.
Spaced repetition
Cards you miss come back sooner and cards you know are spaced further apart, so kilo, milli, and nano stick without daily cramming.
Study anywhere
The free plan lets you study in the browser. Plus adds PDF, DOCX, and Anki export for studying on your phone or in another app.
How it works
Upload your notes
Add a lecture PDF, slide deck, or a photo of the prefix table from your textbook.
Generate flashcards
DeckOwl creates question and answer cards covering each prefix, its symbol, and its power of ten.
Study with spacing
Review cards in the browser and let spaced repetition schedule the ones you find hardest.
Prefix cards work best when each one asks for a single fact: the symbol, the power of ten, or a converted value. Start with the prefixes that appear most in your lectures, then add the rest once the common ones feel automatic.
Spaced repetition handles the rest. Prefixes you confuse, such as milli and micro, come back more often until the difference is second nature.

Frequently asked questions
Which SI prefixes should I memorize first for an intro physics course?
Start with kilo, centi, milli, micro, nano, and mega, since they cover most problems in introductory courses. Add giga, tera, and pico once those feel automatic.
How many flashcards should I make for SI prefixes?
Around 12 to 16 cards covers the common prefixes, with one card per prefix showing its symbol and power of ten. Add cards for the units you use so the prefixes stick in context.
Can I export physics prefixes flashcards to Anki?
Yes, the Plus plan includes Anki export along with PDF, DOCX, and CSV export. The free plan lets you study in the browser with 3 generations per month.
