This is pretty cool, it's one of the rare applications I've used where the things I've tried "just work". For example "10 kg to g", "c", "c to km s^(-1)", "c to km/s" all work…

Looks really nice! ≫ exp(2*kg/s) ``` exp(2 × (kg / s)) Conversion error: Cannot convert quantity of unit kg/s to a scalar ``` Excellent! Is there any way I can save a list of…

Well done! Plain and easy to understand interface and excellent use of colour and space. Two suggestions: 1. While I doubt it'll be used very much, consider adding calories for…

This is exactly what I've been looking for for years. A fast easy calculator that's as convenient as a physical school calculator but with familiar programming style input since…

Hmm, I find the auto-associativity to be a bit weird for example: ≫ 1/12 c ``` 1 / (12 × c) = 2.7797e-10 s/m ```

I tried to enter ``` 3 5 ``` which was interpreted as 3 * 5. Seems a bit risky to me :) Otherwise looks neat.

First thing I tried: >> 2 min 35 s + 3 min 54 s = 13920 s²

≫ round(pi * 100000000000000000) = 314159265358979324 ≫ round(pi * 1000000000000000000) = 3141590000000000000 (similar comment by @btown down there about e)

> high precision ``` ≫ e*1e15 e × 1000000000000000 = 2718280000000000 ``` Needs a bit of work, I think.

Nice, but ``` sin (30 rad) sin × 30 rad Unknown identifier: sin ``` Wouldn't it be great if software evaluated things, and if things didn't made sense, considered what the…

I tried to convert 1000 rpm (revolutions per minute) to Hertz (periods per second), but I get ``` Unknown identifier: rpm ```

I really like the UI and seeming wealth of different units. It doesn't look like it supports fluid ounces though. I tried "4 tbsp to oz" and it interprets oz as mass instead of…

Kudos! I would love to see two more things: 1. Propagation of uncertainty.[1] I often yearned for a calculator that automatically propagated uncertainties for me while writing my…

Really great tool! Thanks for the hard work. It would also be really nice to specify custom units, such as ``` ≫ U = 1e-6/60 * kat U = 1.66667e-8 kat ``` Because now it does this…

Too bad it doesn't support complex numbers

Looks really nice! ≫ exp(2*kg/s) ``` exp(2 × (kg / s)) Conversion error: Cannot convert quantity of unit kg/s to a scalar ``` Excellent! Is there any way I can save a list of…

I'm a little confused as to how this improves on GNU units, which seems to support far more: ``` $ cat .units period(len) units=[m;s] 2pi*sqrt(len/gravity) ; (period/2pi)^2 *…

Nice, though I'm still highly partial to GNU Units. In large part as it allows specifying output units, and not just for conversions. Note: if you're on MacOS and are using the…

Very nice on first try -- added to my quick toolbar. Great to be able to intermix metric and SAE units, as there is (very unfortunate) constant use of both in my field of work.…

For those interested on a CLI counterpart, GNU units is more or less the same. The units definitions file is enormous

hmmm, I'm a little bit skeptical about this. I'd be cool to have this as a python script somewhere but I am not quite sure wether I would visit this site whenever I need to…

I have been using Frink for over 7 years. Aside from a calculator with a gazillion units, Frink lets you program in a less verbose Java for other tasks. Graphics are easy too. I…

Nice. This is a lot like (in looks and some functionality) the macOs app, 'Numi' (which I love) : https://numi.io/

I use Python with pint [0] for this. It integrates with numpy. It has support for uncertainty. You can do all calculations Python can, Python math reads like ascii math. It also…
