What is a cheat sheet?
Each cheat sheet is a single print-ready HTML page: clean layout, no ads, no sidebars, print-optimised CSS. Open the page, press Ctrl+P (or Cmd+P on Mac) and choose "Save as PDF" or send it straight to a printer. The cards are designed to fit on one A4 or letter-sized sheet.
When to use a cheat sheet instead of the calculator
- Working offline or away from a screen
- Pinning a reference to a wall or fridge
- Keeping one in the glove box, tool bag or kitchen drawer
- Teaching or sharing with someone who needs the values at a glance
For calculations on the screen, the interactive tool is faster. For values you need repeatedly without typing, a printed card wins.
Frequently Asked Questions
How do I print a cheat sheet?
Open the cheat sheet page, then press Ctrl+P on Windows or Cmd+P on Mac. In the print dialog, choose your printer or select "Save as PDF" to keep a digital copy. The pages are designed with print-specific CSS that hides the sidebar, navigation and footer, leaving only the reference content.
Do the cheat sheets work on mobile?
Yes. Each page is responsive and readable on a phone or tablet. To save as PDF on Android, use the browser's share menu and choose "Print" then "Save as PDF". On iOS, use the share sheet and tap "Print", then pinch to zoom to save to Files as a PDF.
Are new cheat sheets added regularly?
New printables are added when a converter or calculator topic has enough reference data to fill a useful one-pager. If you have a suggestion for a topic that would make a good cheat sheet, use the contact page.
