Sorry to be the party stopper for a really awesome tool, just wanted to let you know that you have a dead butterfly as a logo: http://emilydamstra.com/news/please-enough-dead-butterflies/

Oh, I didn't know that :-)... that's interesting. I'm very much open for suggestions on how to improve the logo. I already went through a couple of iterations...

Wow! The article is eye-opening; worthy of submitting to HN as a news link in my opinion to create more awareness. If you agree, please submit.

I found it through the front page a few weeks back (;

It unfortunately fails my go-to test for these calculators: ≫ 7.8L/100km -> miles/gallon 7.8 L / 100 km -> mi / gal Conversion error: Cannot convert unit L/km (base units: m²) to unit mi/gal (base units: m⁻²)

That's because your unit conversion is invalid. It's entirely possible to construct an equation that computes mi/gal from L/km (or from gal/mi for that matter), but the dimmensionalty of the two numbers clearly disagree. Yes, you can introduce scenarios like yours where "any human" would know what the intended meaning of the question is, but mathematically speaking it's incorrect and encouraging a calculator to perfo…

I don't remember which calculator did this (I think GNU units), but I've seen this handled automatically with a warning saying "Warning: reciprocal conversion"

Very nice! Any plans to add decibel/log-scale units? That would make this even handier.

Thank you! "bel" is already supported ("decibel" also, due to the handling of SI prefixes). Unfortunately, "dB" is parsed as "deci-byte". While this is not really a useful unit, this is on purpose (see https://github.com/sharkdp/insect/issues/67 ) in order to support "kB", "MB", etc. for "kilobyte", "megabyte", etc.

This is worthy of fixing in my opinion. I do see this as a nuance, but if this is what the common usage of dB is, it should be supported.

That's cute. Are there any phone apps which do that? Remember Graphing Calculator? That could use such features. Autodesk Inventor understands units in formulas, but mostly for length and angle. Everything becomes meters internally.

There is a version of Frink(lang) for Android. I don't think there's one for iOS. https://play.google.com/store/apps/details?id=frink.android&...
