Question 1

What units are supported?

Accepted Answer

Bytes, KB, MB, GB, TB, and PB — in both binary (1024-based) and decimal (1000-based) standards.

Question 2

What is the difference between binary and decimal?

Accepted Answer

Binary uses powers of 1024 (KiB, MiB, GiB) while decimal uses powers of 1000 (KB, MB, GB). Operating systems often mix the two.

Question 3

Can I convert very large values?

Accepted Answer

Yes. The tool handles values up to petabytes and beyond within JavaScript's numeric range.

Question 4

What is the difference between KB and KiB?

Accepted Answer

KB (kilobyte) uses the decimal standard where 1 KB = 1,000 bytes. KiB (kibibyte) uses the binary standard where 1 KiB = 1,024 bytes. Hard drive manufacturers use decimal, while operating systems often use binary, which is why reported sizes can differ.

Question 5

Why do file sizes look different on different systems?

Accepted Answer

Differences arise because operating systems may use binary counting (1 GB = 1,073,741,824 bytes) while storage manufacturers use decimal (1 GB = 1,000,000,000 bytes). This converter supports both standards.
