Smidge — Unit Converter

Smidge is a tiny, careful unit converter. No ads, no chatter, no sign-ups — just the answer, at the speed you need it.

Type a number and read the result instantly. Smidge does the math, remembers what you use, and gets out of your way.

WHAT YOU CAN CONVERT
• Length, mass, volume, temperature, area, speed and more
• See every unit at once with the "all at once" view
• Do quick math right in the field — type 3 × 250 + 50 and convert the result

BUILT FOR REAL LIFE
• In the kitchen — density-aware cooking conversions. Cups to grams by ingredient (flour, sugar, butter and more), using USDA reference densities. No more guessing.
• Trades — millimetres to feet, inches and fractions, down to 1/8, 1/16, 1/32 or 1/64.
• Medical reference — blood glucose between mg/dL and mmol/L, shown against standard ADA ranges. For education only, not a diagnosis.
• Currency — handy offline reference rates for quick estimates.

MADE TO STAY OUT OF THE WAY
• Pin the conversions you use most for one-tap access
• Metric or imperial, with adjustable decimal precision
• Works fully offline — everything runs on your device
• No accounts, no ads, no tracking, no data collected

Smidge keeps everything local. There's no backend, nothing to sign in to, and nothing leaves your phone.

A small amount. Measured carefully.
