Science Unit & Constant Mnemonic Generator
Used by developers, writers, and creators worldwide.
The science unit & constant mnemonic generator creates ready-to-use memory aids for five of the trickiest topics in STEM: SI base units, metric prefixes, physical constants, the electromagnetic spectrum, and taxonomy ranks. Students preparing for exams, tutors building revision materials, and self-learners working through a physics or biology course can all benefit. Pick a topic, then choose a mnemonic style — sentence, acronym, story, or rhyme — to match how you actually retain information. Each result includes the full ordered list the mnemonic encodes, so you can cross-check it instantly and start drilling straight away. Pick the unit set you need, choose the mnemonic style, and copy the full mnemonic into a worksheet, slide, or notebook without further editing.

FAQ
what's a good mnemonic for metric prefixes in order
A classic sentence mnemonic maps each prefix letter from tera down to pico — for example, 'The Great Men Kept Helping Doctors Deliver Correct Medicine Nightly Please.' Use the generator's Sentence style on Metric Prefixes to get a fresh version, or switch to Rhyme if that sticks better for you.
how do I remember taxonomy ranks easily
The traditional sentence is 'Dear King Philip Came Over For Good Soup' — Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species. If that one doesn't click, try the Story style in the generator; a narrative with characters often outperforms a dry sentence for long-term recall.
do mnemonics actually help with science memorisation or are they just tricks
Cognitive science research consistently shows that linking new information to vivid, rhythmic, or narrative cues improves recall — especially for ordered lists like unit prefixes or spectral bands. Mnemonics work best when you write them out a few times and test yourself within 24 hours.
