Unit Converter Kit, with 76 ways to measure things
A broad unit-conversion tool covering 504 units across categories from length and temperature to radiology, typography, electricity, and data transfer.
Field notes
The site organizes its conversion library into 76 categories and states that 504 units are backed by one table of exact factors. Its coverage extends well beyond household measurements into radiology, magnetism, heat transfer, electricity, typography, and data transfer. The homepage also identifies edge cases rather than flattening them: temperature needs more than multiplication, fuel-economy units run in different directions, and dry measures form a separate family from liquid measures.
