UnitSheet, a spreadsheet that knows what a metre is
An early-access spreadsheet for STEM work that keeps quantities and their units together, checks dimensions, and converts compatible values automatically.
Field notes
The public preview lets visitors test expressions before creating an account, including addition, division, and energy calculations. The homepage says compatible arithmetic follows the first term’s unit, while incompatible dimensions return an error; its stated reference set contains more than 280 units across 61 dimensions. Core quantity arithmetic, formula evaluation, and workbook storage are described as implemented, with interface and collaboration features still maturing.
