Choosing the right unit
Match the unit to your audience: SI for scientific work, imperial for US domestic contexts. When in doubt, present both — the Temperature Converter makes that trivial.
Extremely small or large values are easier to read in scientific notation. The Temperature Converter switches to scientific format automatically when a plain decimal would be hard to read.
