> Curiously, I'd say 90% of the time I use Google is for math. If I'm typing a complex math expression (especially with units), Google tends to do much better than DDG. I used to use google for this too, until I discovered GNU units [1]. GNU units is vastly superior to Google for complex formula and runs quietly in my command line. Some examples: Q: What's 72°F in °C? A: $ units "tempF(72)" "tempC" 22.2 Q: How many teaspoons are in a tablespoon? A: $ units "1 tbsp" tsp 3 Q: What is the total energy content of 1 kg or uranium, burned completely in a breeder reactor? A: $ units "1 kg /(238 g/mole) * 200 MeV * 6.022e23 / mole" "MW*days" 938 Megawatt-days Q: How many femtobarns are in a square teraparsec? A: $ units "teraparsec^2" "femtobarn" 9.5e99 (very close to a google) Q: How many hectares are there in a baker's dozen of mm^2? A: $ units "10 bakersdozen mm^2" "hectares" 1.3e-08 [1] https://www.gnu.org/software/units/manual/units.html https://www.gnu.org/software/units/manual/units.html
