When I went to download Google's Material Design color palette, I was presented with what it called a 0.02 MB download. After chuckling on how an algorithm might not've been written properly, I realized that this entire site was engineered in great detail and wondered, should users really ever see Bytes, Kilobytes, or Gigabytes as units in a download?
The vast majority of items with a download button are between 1MB and 2GB (in my experience), so it shoudn't be unreasonable to be only displaying 0.2MB, 1MB, 20MB, 1294MB, etc. instead of 200KB o 1.2GB, etc. (note I'm using Megabytes and not Mebibytes, here. After all, this is more a question about end-users, who tend not to know the distinction in my experience)
