What it does
This online pixel (px) to rem converter can convert pixel units to rem units. It calculates the corresponding rem value based on the root font size you set. It's ideal for responsive web design. In addition, it supports various other unit conversions, including px to rem, rem to px, and em to px. Some tools support batch conversion of text content. For example, if you have a block of CSS code containing many px values, simply copy the code into the batch conversion input box.

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
