UnitCraft: Workshop Tech Calc

UnitCraft is an offline technical calculator for machinists, mechanics and technicians. It puts the shop-floor numbers you look up every day in one fast, high-contrast app that works without an internet connection. WORKSHOP TOOLS • Fraction & Socket: convert fractional or decimal inches to mm and back. See the nearest 1/64" fraction with its error, and the metric or SAE socket that actually fits. A socket that fits is preferred over a closer one that doesn't, and loose fits are flagged as a rounding risk. • Tap & Drill: tap drill and close/free clearance hole sizes for ISO metric coarse and fine, UNC and UNF threads. Search, filter by standard and star your most-used threads. • Spindle RPM & Feed: RPM from cutting speed, tool diameter and tool material, with warnings for handheld drills and CNC. Feed for drilling (mm/rev) or milling (feed per tooth × flutes), with the resulting feed rate in mm/min and in/min. GAUGES & WIRE • AWG wire gauge: diameter, cross-section, ampacity and copper resistance. Enter a metric size such as 2.5 mm² to get the safe and the nearest AWG size. • Sheet metal gauge: thickness and weight per gauge for steel, stainless steel, galvanized steel and aluminium. CONVERTER • Pressure, torque, length and temperature. Every unit is shown at a glance, both fields are editable, and tapping a row copies the value. BUILT FOR THE WORKSHOP • 100% offline: no account, no ads, no tracking • No permissions required • High-contrast dark theme and large touch targets, readable with large system fonts • English and Turkish interface Feed, speed and ampacity values are starting points based on standard tables and common workshop practice. Always check them against the tool manufacturer's data and the applicable standards and codes. UnitCraft is developed by Klogsoft.
