How many bytes are in a kilobyte?

In the decimal (SI) system used for storage marketing, 1 kilobyte (KB) equals 1,000 bytes. In the binary (IEC) system used internally by most operating systems, 1 kibibyte (KiB) equals 1,024 bytes.

What is the difference between a kilobyte (KB) and a kibibyte (KiB)?

A kilobyte (KB) is 1,000 bytes, the decimal unit manufacturers use to advertise storage. A kibibyte (KiB) is 1,024 bytes, the binary unit your operating system often uses, which is why a drive can look smaller than advertised once it's plugged in.

How do I convert GB to MB?

Multiply the gigabyte value by 1,000. For example, 2.5 GB equals 2,500 MB.

How do I convert Mbps to MB/s?

Divide the Mbps value by 8. Internet speeds are sold in megabits per second (Mbps), while file sizes and download progress are shown in megabytes (MB), and there are 8 bits in a byte.

Why does my hard drive show less space than advertised?

Manufacturers advertise storage using decimal gigabytes (1 GB = 1,000,000,000 bytes), but operating systems often report it in binary gibibytes labeled as GB (1 GiB = 1,073,741,824 bytes). A 1,000,000,000,000-byte drive shows as about 931 GB in Windows for this reason.

How long will it take to download a file?

Divide the file size in bits by your connection speed in bits per second. This calculator does that automatically: enter the file size and your connection speed to get an estimated download time.

How many GB are in a TB?

There are 1,000 GB in 1 TB (decimal), or 1,024 GiB in 1 TiB (binary).

What is the difference between Mb and MB?

A lowercase 'b' means bits, and an uppercase 'B' means bytes. Mb is megabits, commonly used for internet speeds; MB is megabytes, commonly used for file sizes. 1 MB equals 8 Mb.
