CASIO - FX-115MS+ Scientific Calculator Review

Average Reviews:

(More customer reviews)For many years, I used a Casio Scientific that had no battery. It meant that I had to be sure that there was some light (not much at that) in order to use it. It was stolen and I've been trying to replace it. This models description didn't indicate that it had or needed a battery so I bought it. It has a battery and indications from the (enclosed) directions seem to indicate that is required and must be replaced when it goes dead. there is little more irritating to me than having to find a special battery for something for many reasons. That, and the awkward "case" are the only faults I find with it but they are enough so that I find myself willing to give it away soon (before the battery ages or the case gets lost). I should point out that the calculator depicted FX1115MSPLUS doesen't have the BIG round button mine has and mine doesn't call itself ...PLUS. the one in the picture might be the one I ordered but didn't get. ??? I sure hope someone reads this... .

1-Step Instant Metric Magic Conversion Calculator Pro Review

Average Reviews:

(More customer reviews)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! [...]
