About Taper Calc
Most online tools for this task bury what you need behind ads and forms. Taper Calc 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. It is one of about a hundred utility tools that share the same philosophy: do one thing, do it well, get out of your way.
