Before technology, slide charts like these were common for so many different uses. This vintage slide converts Metric to English in just about all ways possible. Some today call it a ‘paper app’ which we think is quite clever.
Made by the Slide Rule Corpration in West Chester, PA, it will convert metric weights, fluids, temperatures, linear, volumes and more to English with just a quick slide.
You don’t have to be a geek to appreciate how handy this is to keep tucked away in your kitchen or office for reference.
