Free Shopping Calculators and Tech Tools by Techodom<
Techodom Tools is a free set of browser calculators for shoppers. The TV Size Calculator gives a screen’s width, height and seating distance; a 65-inch 16:9 TV is 143.9 cm (56.7 in) wide. The Unit Price Calculator compares two packs by price per kg, per L or per 100 items. Both tools need no sign-up and store nothing.
