    Wow! This Sharp EL344RB calculator does everything. It can actually calculate fractions. And it can mix decimals with fractions. It also has metric and USA measurement conversions as well as foreign currency buy / sell conversion. For a small calculator it has a large display. Many other calculators loose their currency conversion entries after they time out. Not this one. You can pick it up 2 days later and it still has your foreign conversion detail in memory. It also has a constant multiplicand - great for figuring your net pay without repeatedly entering the Gross amount. It has dual power and comes with a nice folding vinyl case. This is not a complicated device. Some of the features are not intuitive, but within 30 minutes you can learn all of the features. No engineering degree from MIT required. Any 12yr old with a half a brain can use this, It's quite accurate.it's calculations are always correct. In fact it's a great toy. I'm always trying to fool it. For the price, a bargain, without having to drag out my laptop or tablet and call up the correct apps. I wholeheartedly recommend this calculator.

    5.0 out of 5 stars Great little calculator !
    Reviewed in the United States on June 28, 2020
    Color: WhiteVerified Purchase
    Happy circumstance: I remember enough arithmetic from my school days, to do basic calculations with pencil and paper, or in my head (cashiers are always amazed ... 8-) ).
    But as an American interested in European and world affairs, the calculations I cannot do easily are: American measurements to Metric, Metric to American. A never-ending source of annoyance.
    This little calculator solves the problem very well. Must own 4 of them (2 I can't find: also annoying).
    My only criticism would be: the labels for the various types of calculation can be difficult to read, because I have to take off my glasses (very near-sighted, and getting to an age, sad to write ...).
    Definitely a "Don't leave home without it!" gadget. Also much handier than the iPhone.

    Verified Purchase
    Lot's of great features that are easy to use and hard to find in other user friendly units. I have been using mine for a couple of years now and in fact bought two of them, one for my office and one for my hobby workshop. Liked the first one so much I ordered a second one from Amazon shortly after using the first one. The 10 digit display is very nice and the metric conversion feature is easy to use, going in either direction. Perhaps the most interesting feature is the fraction converter. How many times have you wondered what some fraction would be when displayed as a decimal number, or vice versa? This calculator easily does that. I use it all the time in my home office and workshop for household or model hobby needs. This is the most useful general purpose calculator I have in my house.

    5.0 out of 5 stars Actually an improvement over the 344g model
    Reviewed in the United States on March 27, 2013
    Color: WhiteVerified Purchase
    This 344R replacement for the 344G is actually an improvement. With two of the old versions now on their last legs after 10 years of daily use, it is good to find a close replacement. The new battery back-up feature is in addition to the old version solar powered-only unit. The buttons and conversions are basically the same as the old version. It adds algebraic functions and currency rate conversions, useful for foreign money rates. If it lasts as long as the old version, money well spent. revision: just realized that the new version goes out to 10 digits, vs. the old version of only 8 digits. Something I need regularily.

    2.0 out of 5 stars Best small calculator I could find, despite some new features being a bit confusing
    Reviewed in the United States on May 18, 2017
    Color: WhiteVerified Purchase
    This solar+replaceable battery 10 digit calculator replaced a failed earlier model I'd used happily for a decade. This new version includes two powerful additional abilities: metric conversions and decimal to fraction conversions. Unfortunately, the added abilities are not completely intuitive for an infrequent user like me, so I'd have preferred doing without them in favor of a bigger display or battery. That said, it's still the best small and thin more-than-eight digit calculator I could find now, and so long as I keep its manual handy I can definitely do lots of useful new things with it not possible on earlier models.

    Update 4/19/2021: I discovered today that its battery has failed. It turned out to be an LR1130/AG10 1.5v alkaline battery, which does not appear to actually be rechargeable, so the solar feature doesn't appear to add any value. In addition, I've never been able to use the advanced conversion features without checking the manual every single time, so am replacing this calculator with a simpler 12 digit model. Reducing from 4 to 2 stars.

    5.0 out of 5 stars Nice Calculator, Good Metric Conversion
    Reviewed in Canada on December 5, 2023
    Color: WhiteVerified Purchase
    This is a normal calculator with the addition of many function buttons for converting between metric and imperial measurements, e.g., square meters to square feet, liters to gallons, km to miles, lbf./sq. inch to kilopascals, Fahrenheit to Celsius, kilocalories to kilojoules, and many others. This involves pressing the number in question, a to metric or from metric key, and the function key appropriate to the conversion desired; a bit awkward but reasonably quick anyway. There are 22 different conversions available (though one I would have liked that wasn't there was lbf. to newtons). The calculator itself is both solar and battery powered and has basic math functions, though it would have been more useful to me if it had an ability to do exponents other than square roots. As it is, a nice device to have handy, especially if you find a scientific calculator too complicated.
