What are kilobytes and bytes?
A kilobyte is 1,000 bytes (decimal), a common unit for small files. A byte is 8 bits, enough to store one character of text. 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 bytes
1 KB = 1,000 B. To convert, multiply the number of kilobytes by 1,000. For example, 5 KB = 5,000 B, and 20 KB = 20,000 B. To go the other way, multiply bytes by 0.001 (since 1 B = 0.001 KB).
