Hi,
Just a quick email to say what a good web site you have. The tables of measurement units must have taken a good while to compile!

Cheers,

Hey! I find your conversion site to be extremely helpful. I do a lot of calculating in my position as a dispersion modeling supervisor at Ohio EPA.

Hi
Very good conversion page, however I would like to understand better why...

If a US Gallon has 128 fl oz and a UK gallon has 160 fl oz this does not correspond to their conversion factors to litres, where US is 3.785 l = 1 gal and UK is 4.546 l = 1 gal so the quotient is 4.546/3.785 = 1.2010568 and 160/128 = 1.25??

There appears to be a 20% difference in actual volume and a 25% in fl ozs.
Is this due to minims or what?

Thanks for your help

[Answer supplied (US and UK gallons are different sizes, have the same number of pints but different numbers of fluid ounces per pint all which make the fluid ounces different sizes also.). Ed:]
I absolutely adored your website!

Terrific unit conversion calcualtor! I'm sending a link to your page to all my coworkers.

Thanks for providing a quick reference for converting figures. I sell recognition and promotional products in Ohio. I need to be able to convert thicknesses of plastic bags to let my customers know the difference between gauge and mil. And I need to figure shipping carton sizes based upon mil thickness of magnets.

Once again thanks,

I just wanted to say that I found the Foot Rule the best unit conversion site I have visited. Very nice work, the thumbwheel is a neat touch.

I have used you conversion program on several occasions and find it easier to use than other conversion programs that I currently own.

Is the program available for purchase?

I have just used your site for the first time and emailed a couple of questions. At first I assumed it was a university site or public service site. WOW, you provide a terrific and wonderful service. Thank you for this exceptional site.

Hello All,

I've reviewed hundreds of unit conversion sites out there, and yours is by far the most impressive.

I (more accurately, the small start up I work for) need a database of conversion factors for virtually every unit in the world. Yours appears to come very close to this requirement. Do you ever license or sell your conversion information in a format which I might be able to easily import into my database?

If not, can you point me toward a reference which might contain a list of conversion factors as extensive as yours?

Thanks a Lot!

Greeting from New York City,
I'm writing to comment on your site, JavaScript Unit Conversion Calculator . I think it's absolutely the most interesting, educational, thorough, fascinating thing I've ran into while on the Internet. Frankly, I was so fascinated by it, I started playing with the conversion table of mass to see just how thorough and accurate the information was and as you can imagine, I was entirely dumbfounded. I am from the US and as you know, we don't use the metric system which is unfortunate but it's the way this country is. Anyhow, I can't tell you how helpful your site was in helping me make the conversions within various metric units I wasn't taught in this country. I truly appreciate it, and trust me, I'm telling everyone who's metric-ignorant (as most US Americans are) about this site!

Keep up the wonderful job!

You really have a good web site that really helped my homework. But do you have a table unit of temperature. I really need it and its my only thing left that I dont have. Thanks for your kind consideration.

I just wanted to say thank you for all of your work in putting this site together. Myself and several of my classmates have used it in completing a tedious engineering class assignment. Many thanks from the University of Arkansas Mechanical Engineering Students.

This site appeared to have the most comprehensive list of conversions available which is why I have it bookmarked. I need to convert units very frequently. It takes much less time to call up a bookmark and find the conversion that I need than to search down a CRC Handbook and page through the conversion tables.

Thanks,

Just want to thank you for a great unit converter. Your site has been invaluable to keep me from getting lost in a jungle of units while spending a year away from Sweden at a US university, which certainly has not gone metric yet.

Again, thank you!

Dear Sirs,

I'm really interested in your pages which are about Units..

I wonder if you have Japanese Version of your pages. If you have some, please let me know.

Yours sincerely,

We are a manufacturer of microscopy precision measuring devices. As a service to vistors to our website (www.boeckeler.com), we are wondering if we could link them from our very simple conversion table to the site below for far more thorough conversions. Would this be all right? This is the page we'd like to link to.

I found your conversion calculators the most useful of the many I've browsed today. Please let me know if this is permissable.

Sincere regards,

I was just trying out your conversion calculator, which is quite nice by the way.

I found something I don't understand. I think there may be an error. I was able to produce the following conversions under mass conversion:

1 Pound (Av) = 1 Pound (Troy) 1 Kilogramme = 2.679 Pounds (Troy) 1 Kilogramme = 2.205 Pounds (Av)

Is there an error?

David L. Rigby, Phd.

[There was, the unit which appeared to be the Pound (Av) was actually the Pound(Ap) with an incorrect description. Correcting the single character of the description from a 'v' to a 'p' corrected the problem. Ed.]
The site is very good.. this is the one I use to do conversions... but I didn't find temperature conversions (kelvin, celsius, the obsolete farenheit and rankin). It would be nice...

The Foot Rule : Unit Conversions

"FootRule.com is a continuously expanding collection of converters, units and measures, data tables and facilities for the student or teacher, scientific or engineering worker, parent and child. The converters provide not only information such as how many miles in a light year, the difference between US fluid and dry gallons, the differences between both these and the UK gallon, but also gives the invaluable background on units, their origin and definitions."

The site is divided into subcategories organized by topic and by type of interface. Users can access information via either a thumbwheel control or a table. The abundant topics available include kinematic viscosity, acceleration, time, flow, and luminance, among others. An easy-to-use form allows visitors to enter desired conversions and choose scientific notation. The site also features tables of physical constants, the periodic table, and imperial capacities for the US and Britain. A nice help page (How to use them), recommendations for browser settings, and a suggestion form are part of The Foot Rule's user-friendly content.

This is an excellent resource for students and teachers in all disciplines of science.

Your conversions tables have been extremely helpful to me. I travel all over the world and work with weights, volumes and lengths. I know I can always get the information I need by coming to your site.....

thank you

R & D John
I am in the import/Export business and find this calculator most effective for converting imperial weights and measures to metric as well as calculating weights & measures for products which have to be placed into ocean containers.

Great program!
