Summary: Bought my first metric converter from university bookstore; becuase other pre med/nsg students were loving it.Saves time when you need to figure doseages /weights/temps ect.Nice to have for double checking orders.I still have my fisrt model(purchased in 1990)& haven't had any problems with it...even after my puppy chewed the bottom left corner loosening the faceplate!When I used this @ work co-workers were wanting one too..
Summary: I bought this calculator for the metric conversion feature. I use a sewing/embroidery machine and software that is made by a Swiss company and the metric system is used for their calculations. I frequently need these measurements converted and this was the perfect solution.
Summary: I can convert from English to Metric measurments by just pushing a button. It is small enough to carry in my purse. I had a similar calculator for 25 years that was damaged in an accident and thought I'd never find a replacement. This is great.
