What are kilobytes and bits?
A kilobyte is 1,000 bytes (decimal), a common unit for small files. A bit is the smallest unit of digital data, a single 0 or 1. For scale: a photo is a few MB, an HD movie a few GB, and a modern drive holds 1 TB or more. These use decimal (1 KB = 1,000 bytes).
How to convert kilobytes to bits
1 KB = 8,000 b. To convert, multiply the number of kilobytes by 8,000. For example, 5 KB = 40,000 b, and 20 KB = 160,000 b. To go the other way, multiply bits by 0.000125 (since 1 b = 0.000125 KB).

FAQ
What is 1 KB in b?
1 KB = 8,000 b. To convert any amount, multiply the number of kilobytes by 8,000.
How do I convert bits back to kilobytes?
Go the other way: 1 b = 0.000125 KB, so multiply bits by 0.000125 to get kilobytes.
Is a kilobyte bigger than a bit?
Yes — 1 KB is the larger unit, equal to 8,000 b.
Are these digital storage conversions exact?
They use the standard internationally-defined conversion factors. Results are rounded to six significant figures for readability, which is accurate enough for everyday and most technical use.
