Our calculator is designed to let you convert between or within two systems of measurements, (U.S. inch/pound and Metric), with the touch of a single key. It is unlike all other conversion calculators that require programming, prior knowledge of conversion factors and formulas, or memorization of complicated menus and shift key sequences. Our 1-Step calculator is designed from the ground up to make the whole process hassle free and idiot proof!

Our customers in industry, government, education, and at home have found the 1-Step indispensable and we are certain that you will too. We are so confident that we offer an industry leading satisfaction guarantee and return policy.

You can return the 1-Step for any reason within 60 days of purchase for a full refund including original shipping and handling charges (up to $8.95 per order). We will even provide you with a pre-paid return label for a no-cost, hassle free return (up to 2 units) – simply drop the package off at any post office. Fill out an RMA Request for easy return instructions.

Catches and conditions? Nothing tricky. The item must be in resalable condition with all packaging and accessories or a restocking fee may apply. This offer applies only to the 1-Step calculator and only if it is purchased from us directly. Does not apply to orders with custom imprinting.
