While the rest of the world operates in metric, we're still primarily using the old imperial system of measurement here in the United States. But more and more we're seeing metric equivalents: Length (5K marathon), volume (2 liters of soda), weight (40 grams of fat), and temperature (37 degrees Celsius).

Having grown up learning the english system, it's difficult to try to remember all of the conversion factors, especially since we've not made a national dedicated switch and both forms continue to be used arbitrarily.

Sure, a 2 liter bottle of soda is an easy one, but what about centimeters? I can visualize an inch...so how many centimeters are in an inch? 2.54! And what about a 5K race? How many miles is that? Well, exactly 3.106855961 says my 1-Step Conversion Calculator.

What's so fantastic about the calculator is how simple it is to use: The buttons are color coded, individually marked, and well layed out. Conversions are made with the push of only 3 buttons! For example, remember that 5K race we wanted to convert to miles? Press 5, press KM, press MI. That's it and your answer is displayed! Another great feature is the ability to convert 2 variables within the same measurement form. For instance, you can convert cups to gallons. This makes the calculator great for cooking, especially when you want to cut a recipe in half. I gave one to my friend who works at the zoo and has to prepare diets, weigh animals, and dispense medication all in metric. She loves it!

I work in an industry where specification callouts are about 50% metric. Even though you tend to memorize a conversion factor, the going back and forth from metric to english and english to metric can be confusing. Even worse, a single product is marked by the manufacturer with both forms (360 threads per INCH and a 76 MICRON thread diameter)! Because the calculator is so easy to use, I can convert very quickly while talking to a designer on the phone so we're on the same page.

Don't forget the 1-Step operates as a regular calculator, too! I've been using mine for at least 5 years and I love it! [...]

This is a really great calculator while it works. They are an extremely handy if you have to make conversions from English to metric or vice versa. As a field scientist, I need a durable calculator and have purchased five of these for my self and my staff with mixed success. Two have lasted over a year, although one of them stopped working after about two and a half years of use. The other three did not last a year. For some reason the display begins to fail with all of the calculators I have had problems. I'm currently looking for something very similar to this calculator that will last longer. Although they are very handy, their unreliability makes them a poor investment.

When my calculator arrived I was skeptical as to the ease of using it, however I was proven wrong very quickly. In dealing with many international locations the conversion calculator has become an invaluable tool for me as I use it daily.

I use a identical, non-solar version of this calculator many times a day (too lazy to learn by rote all the conversion multiples). It is GREAT and very simple to use. It could look cooler for all the great things it does (and for the money they ask for it) but it has to be the best product of its kind out there for now.
