I want to be able to press a keyboard combination, start typing a mathematical expression that includes units and slightly advanced math (not just a four-function calculator), and get a result immediately, in units that I specify, that I can copy and paste.
- Currently I open Firefox and press Ctrl+K, type in the search box, and it usually gives me a result in the drop-down from Google Calculator. It doesn't always, though, so I press "=" at the end, wait for a result, remove the equals, wait for a result, realize it doesn't understand the way I typed a unit, open the result in a new tab, etc. it sucks.
- Wolfram Alpha is smarter, but very much slower, and the output is all images, not text, and I don't have a quick widget for it, if such a thing could even exist.
- GNU units has a ton of units, which is great, and I can define my own units, which is great, but they have to be written in specific, unintuitive ways, it doesn't handle much advanced math, and I'd need to open a terminal, start units, etc. I hate the command line.
- I wasted a lot of time trying to make front-ends for
unitsin Deskbar and Launchy, but I'm not a real coder and I don't use either of those anymore.
Any other solutions or enhancements of these?
(Cross-platform is best)
The ideal unit-aware calculator would be able to handle all of these:
7 nV/sqrt(Hz) ⋅ sqrt(20000 Hz - 20 Hz) → μV= 0.99 μV
sqrt(4*k*25 °C * 1 kΩ * (20 kHz - 20 Hz))= 0.57357 μV
3.5 billion kilowatt-hours per year= 399.5 MW
60 billion kWh per year= 6.849 GW
1/sqrt(2 mH * 2 nF)= 500 kHz
1/(2*pi*10 kΩ * 22 µF)= 0.7234 Hz
1/(2·π·100 Hz·30pF) → ohm= 53.05 MΩ
−10 dBV + 4 dB + 10 dB − 12 dB → dBu= -5.782 dBu
94 dBSPL → Pa= 1.00237 Pa
54 inches + 2 feet → cm= 198.1 cm
12 V ÷ 141.5 µA= 84.8 kΩ
16 bit * 44.1 kHz * 2 → kbit/s= 1411 kbit/s
1 hundred V / 5 ohms= 20 A
furlong per fortnight → cm/minute= 0.9979
attoparsec/microfortnight → in/second= 1.004
1 ft / speed of sound= 0.89576 ms
