How many Kilobytes are there in a Gigabyte?

1,048,576.

According to the International System of Units (SI), the prefix kilo represents a thousand (10³) and the prefix giga stands for a billion (10⁹). Consequently, 1 gigabyte would contain 1 million kilobytes; however, digital information is based on binary values rather than decimal ones. Therefore, it would more appropriate to follow the JEDEC memory standards, where the prefix kilo designates 2¹⁰ (or 1,024) and giga equals 2³⁰ (or 1,073,741,824).
