Printable formula sheets
The same reference, laid out for paper. Each sheet is a single high-contrast table built to print black-on-white, with the column headers repeating at the top of every page and the breaks falling between topics rather than mid-topic — the one thing a formula page in a browser cannot give you the night before an exam.
Equations are set in real maths, not ASCII. Every row carries a symbol key and the SI unit of every symbol, so the sheet stands on its own once it leaves the screen.
Every sheet
Six category sheets covering all 252 formulas, plus constants and unit conversions.

Physical constants sheet
All 27 physical constants in PhysRef on one sheet, grouped by family, with symbol, value at full published precision, unit and — where the data carries one — the published uncertainty.
84 rows · 14 sections
Unit conversion sheet
Conversion factors for every unit PhysRef converts — 14 measurement categories on one sheet, each unit given as a multiplying factor to that category's SI base unit.
What costs and what does not
The physics is free. The sheet is not.
Every equation, symbol, SI unit, constant and conversion factor on these sheets is free to read on its own page — no account, no paywall, no daily limit, forever. So are the calculators. A sample of every sheet renders for everyone, in the real columns, so you can judge the layout before deciding. Premium unlocks the complete print-ready sheets and the print button.
