Ads make this unusable
Usually I can forgive an ad in a free app, but the ads in this app are so pervasive that you have to sit through a short video to do anything. Click on unit, watch an ad, enter a value, watch an ad, get your answer. Though sometimes it loses your input while the ad is playing and you have to start over! There are other free converters that work much better, skip this one.
