It's super cool, but I'm not sure the explanation of how to calculate Fahrenheit to Kelvin is, uh, accurate. ;-) "By using our Fahrenheit to Kelvin conversion tool, you know that one Fahrenheit is equivalent to 255.93 Kelvin. Hence, to convert Fahrenheit to Kelvin, we just need to multiply the number by 255.93. We are going to use very simple Fahrenheit to Kelvin conversion formula for that. Pleas see the calculation…

Most of units contain very generic description because my goal was to work on the tool rather than the content part. But I will optimize it in the upcoming future since I am one guy managing everything.

> We have so many online tools available to convert Volume units, but not every online tool gives an accurate result and that is why we have created this online Volume converter tool.

Then it converts 231 in^3 to 0.99999994293884 U.S. gal, while 1 U.S. gal converts to 231 in^3.

I wanted to put in a plug for my employer's open-sourced C++ units framework, called Au: https://github.com/aurora-opensource/au The library incorporates dimensional units into the C++ type system with an emphasis on correctness (including considerations for overflow, rounding, loss of precision, etc) and minimal runtime overhead. As a very simple example of what using this library could look like, here is a tiny cod…

Nice, that looks very interesting. I'll remember it in case I need to do some C++ work in the future again!

I developed a similar library for Nim, `unchained` [0]. Thanks to Nim's extensive macro system it's a pleasure to use (from a short look at the `au`'s docs my biased opinion is it beats `au` on usability :) ).

People always mention Frink and GNU Units, but the workhorse of desktop unit-aware calculation is, in my opinion, Qalculate. In addition to being a capable scientific calculator in its own right, its killer feature is the ability to throw 'x' anywhere into an equality, and it will solve for 'x'. AS well as making to/from unit conversion even easier this also often saves you having to rewrite physics equations to isolate the quantity of interest (and thus potentially screwing up factors when eg converting mm^2 to m^2). The composition of units + symbolic calculator is greater than the sum of its parts.

Earlier quoted context omitted.

Tableware sets in the US commonly come with at least two different sizes of spoon. These usually bear no relation to the "measuring spoons" used to measure volume, though they are handy for stirring tea or eating soup (for the small & large spoons, respectively). For people who cook in the US, a set of "measuring spoons" is a very common kitchen tool. "Teaspoon" and "Tablespoon" are units of measurement of volume, no…

The one you stir tea with is also probably smaller than a teaspoon (probably about half a teaspoon).

Yep, they're usually completely unrelated to the units of measure.

Thanks for the feedback. This is why I shared it here so that I can improve it based on the feedback. I have fixed it.

I agree that it's most commonly an expression of area. I think the length alternative is valid but pretty rare by comparison.

I've never heard it used for area. "Length of x football fields" is the only comparison I've ever heard in the US.

Thanks for feedback. Added football field to the length category.

I will add it by today. It will be available in Area category by tomorrow. Thanks for letting me know. I just add units as soon as somebody let me know by twitter or email.

Funny, I would have looked in the length area, as that's how it's usually used. Part of the problem is that first you have to decide if it's 100 yards or 120 yards.

I chose 120 yards and added that to length category.

I've never heard of anyone comparing to a football field in the Area domain. Of course this is cultural, but at least in the US - the length is what is commonly compared.

Definitely country-specific, I'd expect it to be used to describe areas (and football stadiums be used to describe "number of people"). But footy fields in Australia are typically oval shaped! "Olympic swimming pools" can be used for length, area or volume (but "Sydney Harbours" are only used for volume). PS just tried the tool and couldn't find any of the above "units", not even "football fields".

just added football field to the length. I will look for the units that you have mentioned. If they are widely used, will definitely add them.

You will see the link just before the share buttons to switch conversion.

Still don’t see it (iOS, both iPhone and iPad). I see 5 circular buttons: Facebook, LinkedIn, Twitter, WhatsApp, and a “Copy url to clipboard” one.

Just select any two units... the yellow color text will popup as shown in the image.
