Wish there were no ads but they go quickly. ### 1/5 — Can not enter a negative value in temperature. *2024-11-03* Can not enter a negative value in temperature ### 5/5 — One Stop unit converter *2021-12-24, version 3.2* Best of best. Never had any issue with this apps. If it charges 07.99 I will buy it. Worth it. Thanks Unit converter++ I think I got his apps free. Am I correct. I’ll pay gor it anytime. No kidding🙂😇😊 ### 1/5 — Not reliable *2019-02-26* 1hp does not equal 1kw. ### 1/5 — Awful!!! *2019-02-21, version 2.0.2* Awful user experience, I would over look the fact every time you click or enter anything you end up with an advert if the conversions were actually correct! Very bad software. ### 2/5 — Conversion Error *2018-11-10* 700m is not 2100 feet. It’s close, but not quite. ### 1/5 — Faulty calculator display *2018-05-18* The weight converter works but feels the need to shorten any weight using scientific notation which is unnecessarily confusing. Perhaps put a 2 decimal limit on weight so this doesn’t happen. ### 1/5 — Inaccurate, too many adverts *2018-05-01, version 2.0.2* Rubbish! Can’t convert ft to cm 10’ 6” should equal 320.04 Using this l tried 10.5 ft it converted 283 cm. Not worth any stars but can’t select none ### 2/5 — Ads are too numerous *2018-03-30* I understand that this is a free app, but it becomes practically unusable with the forced ad watching. ### 1/5 — Failure In More Ways Than One *2017-01-31, version 2.0.1* Not only do you need to contend with annoying banner adds at the bottom of the screen, the app automatically launches adds in Safari. Necessitates wasting time exiting brouser and returning to app. Secondly the app converted 365 degrees farenheit as 10.7... degrees celsius. Total rubbish in more ways than one!!! ## Frequently asked questions about Unit Converter ++ ### What units can Unit Converter ++ convert?
