Cobalt Gauge: Unit Converter

Cobalt Gauge is an offline unit converter for length, weight, temperature, volume, area and kitchen measures. Sixty-five units sit across six categories, and a live gauge dial sweeps to the result as you type, so you can see the answer as well as read it. SIX CATEGORIES, SIXTY-FIVE UNITS • Length from nanometres to nautical miles, weight from milligrams to long tons. • Temperature in Celsius, Fahrenheit, Kelvin and Rankine, converted with real offsets rather than a plain ratio. • Volume and area for both metric and imperial work, including US and imperial gallons kept apart. • Pick any pair in a category, then flip the direction with one tap. CUPS TO GRAMS — A KITCHEN CONVERTER THAT KNOWS INGREDIENTS • Forty-two pantry staples carry their real cup, tablespoon and teaspoon weights. • A cup of all-purpose flour is 125 g and a cup of honey is 340 g; Cobalt Gauge uses the right one instead of treating every ingredient as water. • Flours, sugars, dairy and fats, grains and nuts, and baking staples are grouped so the one you want is quick to find. OFFLINE UNIT CONVERTER — NO WIFI NEEDED • Every factor and ingredient weight is built into the app, so conversions work in airplane mode, on a plane, in a basement kitchen or abroad. • The release build requests no permissions at all and makes no network requests, so nothing you convert leaves the phone. • The app carries no advertising, no in-app purchases and no accounts. PRESETS, PINS AND HISTORY • Twelve quick presets cover the conversions people reach for most. • Pin the pairs you use daily and they stay one tap away on the converter. • The last three hundred conversions are kept in a local history you can scroll, reuse or delete entry by entry. • Nine badges and a streak counter track how much you have converted, if you like that sort of thing. BUILT TO BE READ • Choose your decimal precision and whether large numbers are grouped. • Show full unit names instead of symbols when the abbreviation is ambiguous. • A reduced-motion setting stills the animations, and text scales with your system setting. • A dark cobalt interface with a high-contrast amber readout, drawn to stay legible in a bright kitchen. Cobalt Gauge keeps six categories, a pantry table and three hundred past conversions in your pocket, and none of it needs a signal.
