Hobbies & Crafts Calculators
The small, awkward sums that come up in the middle of a project. Work out how many skeins a knitted or crocheted project takes, how many sheets of scrapbook paper to buy and how to cut them, the GH, KH, TDS and pH targets for a shrimp tank, the kerf, taper and tool offset for a waterjet cut, and the frequency of any note for piano tuning in equal temperament or just intonation. Each calculator shows the formula, so you can adapt it to your own project.
