Data & digital converters
MB, GB and TB, internet speed (Mbps to MB/s), pixels and DPI, and aspect ratios. Every tool below is free, works instantly in your browser and explains the formula behind the result.
Digital units trip people up because of bits versus bytes and decimal versus binary prefixes. Internet speeds are sold in megabits per second while downloads show megabytes per second, and storage makers use 1 GB = 1,000 MB while operating systems often count in 1,024s. These converters make the difference clear and also cover print resolution (pixels, inches and DPI) and screen aspect ratios.
