UnitSheet, the spreadsheet that checks your units
A unit-aware spreadsheet for scientists, engineers, and students, where cells store quantities with their units and formulas enforce dimensional correctness.
Why it surfaced
UnitSheet supports more than 280 units across 61 dimensions, automatically converting expressions such as 5m + 3ft while rejecting invalid operations such as 5m + 3s. It is still in development, but the narrow premise is unusually clear: prevent spreadsheets from quietly producing meaningless numbers.
