About Metric System
Most online tools for this task bury what you need behind ads and forms. Metric System takes the opposite approach: load the page, do the job, leave. The goal was to keep the path from "open the page" to "get the result" as short as possible. No mandatory account, no cookie wall, no upsell at every step. If you find yourself doing this regularly, the rest of the utility suite covers most adjacent tasks with the same approach.
