How to Convert Kilobytes to Bytes
To convert decimal kilobytes to bytes, multiply the number of kilobytes by 1,000. For example, 5 kB multiplied by 1,000 equals 5,000 bytes. This is the decimal definition used for the kilobyte.
For binary data, the corresponding unit is the kibibyte (KiB), which contains 1,024 bytes. Therefore, 5 KiB multiplied by 1,024 equals 5,120 bytes. The distinction between kB and KiB is useful when precise data-storage measurements are required.
Kilobytes to Bytes Formula
The decimal formula is bytes = kilobytes × 1,000. For example, 10 kB equals 10,000 bytes and 25 kB equals 25,000 bytes.
Kibibytes to Bytes Formula
The binary formula is bytes = kibibytes × 1,024. For example, 10 KiB equals 10,240 bytes and 25 KiB equals 25,600 bytes.
KB and KiB Explained
A decimal kilobyte, written as kB, contains exactly 1,000 bytes. A binary kibibyte, written as KiB, contains exactly 1,024 bytes. Although KB is frequently used informally to describe both measurements, kB and KiB are technically different units.
For example, 1 kB equals 1,000 bytes, while 1 KiB equals 1,024 bytes. If a value is given simply as KB without specifying the measurement system, check the context to determine whether a decimal or binary calculation is intended.
