Jewelers often need to convert between units for price calculations and appraisals, but some of the weight/mass units are esoteric to the industry and are not present in many calculation tools.

Jeweler's Unit Converter meets that need by allowing quick conversions among the following units on both the iPhone and the Apple Watch for:

AVOIRDUPOIS (Imperial weight): grain, dram, ounce, pound

METRIC: microgram, milligram, gram, kilogram

TROY: carat, pennyweight, ounce, pound

ANCIENT: Roman drachma, Greek drachma, Israeli sheqel, Chinese tael

Now, you can enter the calculations on an Apple Watch and display the results on a paired iPhone, using the iPhone as a second screen when working with sellers/buyers.
