Also please be aware not all locals use "." as thousands separator. About half of the world [0], including we here in Germany, actually uses the dot as decimal separator. Thus your number "4.414 MB" actually looks confusingly close like ~4.41 GB to me on first sight. An easy way to avoid this is to not rounding to three digits after your only dot or comma.
