FAQ
- Does it work offline?
- Yes. Every conversion is calculated on your phone. The internet is only used to show ads.
- How do I convert feet and inches to cm?
- Open Length, pick Feet + inches, and type the feet and inches in the two boxes. Centimeters and every other unit appear right away.
- How many grams are in a cup of flour?
- About 125 g for a US cup of all-purpose flour. Convela's cooking converter lets you pick the ingredient, because a cup of sugar (about 200 g) or butter (about 227 g) weighs differently.
- Does it have live exchange rates?
- No. Convela does not download rates. You type the rate your bank or card gave you, and the app shows the date you entered it.
- Can I change the number of decimal places?
- Yes. Choose Auto, 0, 2, 4 or 6 decimal places, turn the thousands separator on or off, and set inch fractions to 1/8, 1/16, 1/32 or 1/64.
- Does it have Korean units like pyeong and geun?
- Yes. With the app in Korean, pyeong, geun, don, ja, ri, hop and doe appear in their categories. Pinned Korean units stay visible in any language.
- Are there ads?
- Yes, Convela is free and supported by ads. A full-screen ad never appears when you open a pinned conversion, the widget or a recent conversion.
- Do I need an account?
- No. There is no sign-up. Your pins, history and rates stay on your phone.
