The HP-20s is a great calculator. It features easy-to-use algebraic entry and a built-in program library of over 100 built-in scientific and mathematical functions. This powerful built-in program library eliminates the need to input frequently-used functions such as root finder, Simpson’s Rule of integration, complex number operations, 3x3 matrix operations, quadratic formula, and curve fitting programs. When using the HP-20s, these features are available at the touch of a key.
Essential trig and math functions for scientific applications are of course available. Sine, cosine and tangent, or exponential, natural log and antilog functions are only a few of the functions that can be used with the 20s.
The HP-20s performs English / metric conversions and fast conversions for mass, distance, volume and temperature.
Introduced in 1989, this calculator belongs to the last rock solid series of calculators produced by Hewlett-Packard at the end of 90's. You can place it in the pocket of your shirt and forget about it. Thin, light and efficient, you will appreciate its black stylish dress! HP made its name on calculators and this model is one of those that reminds us why!!!
The HP-20S has been produced first in USA and Singapor (we can identify it because it shows 5 rubber feet on the back) and secondly in Indonesia (this one shows 3 rubber feet only on the back). The american and singaporian models are the one to look for, particularly if you are a collector (USA one is the best). Keep an Indonesian model if you like variations.

Been using the HP 20S for 20 years now, Found there is no other match in the scientific Caluculator, The Metric conversion is just one operation. Really sorry HP stop making these. I own a machine shop and buy about 10 of these a year for my employees. We have tried so many different types none match the HP 20s. Problem is once was $35 for a new one, a used one can cost as much as $100

Hewlett Packard HP 20S Scientific Calculator
) The HP 20S is an excellent Calculator. It is a do-it all scientific calculator, and despite being Algebraic Entry is very useful and compact. The button feel and accuracy are very attractive features of this calculator.
*Self test by Pressing the [C] key and [y^x]. Press any key and begin the keyboard test left to right and top to bottom.
*Reset by pressing [C] and [LN].
If you're looking for RPN, buy the HP32sii- they look very similar, but inside they are not. The 32sii costs twice as much, but is worth it.

Needed a new calculator of this type for my son (science/math) -- his old one had been stolen. VERY happy to find the model he wanted, and to get a replacement so quickly.
Good communication
Thanks

Got it on time. Very good. It is made in the USA. I am trying to put in more words. Ebay requires at least 100 characters to review this. You see I have to write and write. Thanks for reading.
