How many converters does Panglify have?
Panglify has 77 converters and calculators across 25 categories, from length and weight to data storage, pressure and time zones. New tools are added regularly, and each category page shows what is coming next.
Are all the converters free to use?
Yes. Every converter and calculator on Panglify is free, needs no account and runs in your browser, so the values you type are not sent to us.
How are the converters organized?
Into four collections: Measurement & Units, Science & Engineering, Digital & Data and Everyday & Lifestyle. Each collection holds categories such as Length or Pressure, and every category page has a multi-unit converter plus its individual tools.
How do I find a specific conversion quickly?
Type part of it in the filter on this page, for example “psi” or “cups”. The homepage search also understands phrases like “5 kg to lbs”, and pressing / on any page opens it.
Where do the conversion factors come from?
From the official definitions of each unit: the BIPM SI Brochure, NIST SP 811 and Handbook 44, the 1959 International Yard and Pound Agreement, IEC 80000-13 and W3C CSS for screen units. The details are on our how we verify page.
