File Size Converter vs UnderMB

Convert any file size and finally know what the number means. Type a value in bytes, KB, MB, GB, TB or PB and get the exact answer both ways — live, as you type. Most converters give you a rough number and stop there. File Size Converter shows the exact byte count, switches between decimal (KB, 1000) and binary (KiB, 1024) in one tap, and explains why a "1 TB" drive shows less space once your computer counts it. No rounding surprises, no guessing. WHAT YOU GET - Instant two-way conversion across bit, byte, KB, MB, GB, TB and PB - A one-tap switch between decimal (1000) and binary (1024) so you always use the right unit - An all-units breakdown that shows the same size in every unit at once - Transfer-time estimates for any file over 4G, 5G, Wi-Fi or fiber - A storage planner that shows how many photos, songs and hours of video fit in a drive - A plain-English reference that clears up bits vs bytes, Mbps vs MB/s, and the missing-space mystery PERFECT FOR - Anyone comparing drive or phone storage before they buy - People downloading or uploading big files who want a real ETA - Developers and IT folks who need exact byte math - Students learning how data units actually work WHY NOT JUST SEARCH IT ONLINE A quick web search rounds the answer and ignores the binary-vs-decimal gap that makes your storage look smaller than the box promised.
