Yesterday I launched a website called The Ultimate Unit Converter. It's a unit conversion tool that anyone can contribute to (a bit like wikipedia). This came about because I had previously made SensibleUnits.com and didn't have time to implement all the great suggestions people would send me.
Many years ago I used to post on the old BA forum (although I was mostly a heavy lurker), and was always impressed by the intelligence and knowledge of posters there. Hopefully I'm now right in thinking that some of you might be interested in contributing to this project. It would be fantastic if you could add any scientific units that are missing (any non-length units, for a start!), and also submit any real objects that you think might make useful comparisons. Cheers! P.S. My sincere apologies if this counts as spamming or such. |

Looks interesting though a bit less useful than Google's calculator function.

I think he means that you could convert a 15 kilometer wide meteor to an amount of school busses or State of Texases.

Oooo is there a 'sticks of dynamite' converter? Everything on History channel and most shows on Discovery convert things to 'sticks of dynamite'.

Online Conversion has been doing an absolutely fantastic job for many years.

Google's calculator calls that 1 mile.
I think that conversion was defined the wrong way around in his program, trying to use 1 cm=0.3937" which is wrong. 1.609344 km = 1609.344 m = 1760 * 0.9144 m = 1760 yards = 1 mile by definition through the definition of the yard as 0.9144 m Just checked, using 1cm=0.3937" is wrong in the wrong direction and makes it 0.999998 mile. I have no idea what goes wrong with his program other than obviously using insufficient precision for the number of digits presented.

Is there an online source of major unit conversions which is carried out to full precision, including +/- amounts after a certain decimal place?

I still prefer non-web applications for this type of thing as I am not always connected
The best software freeware converter I have found is Convert for Windows

For any actual use it doesn't matter. I think I know were the number in the result came from, but I have not idea where that formula came from, it is really messed up. (1/0.3937*36*1760)/160934.4 = 1.000002000004000008000016000032000064 . . . cute decimal expansion BTW. With units ((1/(0.3937 in/cm))*((36*1760)in/mile))/160934.4cm = 1.000002... mile-1 1.000002 is definitely a possible answer I will include from now on in any multiple choice exam I get to write where the question is how many miles is 1.609344 km ![]() 0.999998 will be another. The last three will be 1, 3.14159 and rhubarb.

Since it supports furlongs per fortnight, it should also include Knuth's "Potrzebie System of Weights and Measures."
I suppose I could do that, but it would take, like, effort. Fred

Actually I think the real problem is that he's using 32bit reals to do the calculations.

I use a spreadsheet I made.
The units are selected via drop down box, then it runs the conversions based on the values next to those units on a list below the table. It's sort of ugly, but covers all the basic needs.
