Frequently asked questions
Does Metrix convert as you type?
Yes. Metrix has no Convert button. Enter a number and every row on the screen recalculates instantly, so you see all the conversions at once.

Over 80 units across 14 categories. Length, Weight, Temperature, and Time are free; Currency, Sizes, Volume, Cooking, Area, Speed, Torque, Energy, Pressure, and Digital Storage are part of Pro.
How does live currency conversion work?
Metrix converts between 80+ currencies using rates that refresh daily and are cached offline, so your last rates still work with no connection. Your home currency floats to the top automatically.
Is Metrix free?
Four categories (Length, Weight, Temperature, Time) are free forever with no ads. Metrix Pro is a one-time $5.99 purchase, with no subscription, that unlocks the other ten categories plus live currency, unlimited favorites, and conversion history.
Can I do math inside a conversion?
Yes. The inline calculator lets you type an expression like 2.5*4 directly in the value cell, and every unit recalculates from the result.
Does Metrix handle cooking measurements?
Yes. The Cooking category converts cups, tablespoons, and teaspoons and shows real fractions, so you see 1 3/4 cups instead of 1.7500.
