Compared with the basic calculators manufactured in Taiwan this "Metric converter" feels more solid. The same model with additional solar cells, known as TI-1895, is in daily use on my workbench. The only function in use is the conversion from grams to ounces. Compare it with the slimline Converter introduced 1982.
The TI-1889 traces back to the Canon FC-43 introduced already in 1983.
