Open CAP TheoremYour specific task is reference of business card dimensions for us, europe, japan, and more in mm, inches, and pixels. Open the page, drop your input, get the result — typically under a second.
Your goal is reference for the cap theorem and how databases handle trade-offs. Same approach: paste in, get the result, move on. No account, no upload.
Both tools live in the same category, so the choice depends on the exact subtask. Card Sizes focuses on reference of business card dimensions for us, europe, japan, and more in mm, inches, and pixels; CAP Theorem focuses on reference for the cap theorem and how databases handle trade-offs. Try whichever description matches your goal more closely — they're both free.
Yes — both tools are free for unlimited personal use. The Pro plan unlocks higher limits and batch features but the core functionality stays free forever.
Absolutely. Many users chain multiple tools together — process a file with one, then feed the result into another. Nothing is uploaded, so chaining is essentially instant.
No. Both Card Sizes and CAP Theorem work without signup. We only ask for an email if you decide to subscribe to a paid plan.
