Phone storage, SSD sizes, and data plans are all sold in gigabytes, but the moment you check what's actually free, your device reports megabytes — and the math between them is the 1024-based ladder of binary prefixes. Type 16 into the Gigabytes (GB) box and the readouts cascade: 16,384 Megabytes (MB), 16,777,216 Kilobytes (KB), 17,179,869,184 Bytes, and 0.015625 Terabytes (TB). Each step multiplies or divides by 1,024: gigabytes to megabytes is ×1024, to kilobytes ×1,048,576, to bytes ×1,073,741,824, and to terabytes ÷1024. The fine print: storage marketers sometimes use decimal gigabytes (1,000 MB), which is why a "512 GB" drive shows about 476 GB in Windows — this calculator uses the binary 1024 convention that operating systems report. Photographers estimating RAW photo storage, gamers sizing SSDs, and anyone decoding a phone bill's data usage all climb this ladder. One gigabyte in, five units out, no calculator-app gymnastics required. Streaming math climbs the same ladder: an hour of 4K video at 7 GB means a 16 GB phone holds barely two hours — the conversions above make that painful arithmetic instant.

With the pre-filled defaults — Gigabytes (GB) 10 — the Gigabyte Converter returns Megabytes (MB) 10,240.00, Kilobytes (KB) 10,485,760.00, Terabytes (TB) 0.009766, Bytes 10,737,418,240. Change any input and those results update instantly, so you can see exactly how each number you enter moves the answer.
