Gigahertz to Kilohertz formula

kHz = GHz × 1,000,000

The gigahertz to kilohertz conversion factor is 1,000,000, which is exact by definition. 1 gigahertz = 1,000,000 kilohertz, and 1 kilohertz = 0.000001 gigahertz.

Worked examples

2 gigahertz = 2,000,000 kilohertz — 2 × 1,000,000 = 2,000,000 kilohertz
6 gigahertz = 6,000,000 kilohertz — 6 × 1,000,000 = 6,000,000 kilohertz
10 gigahertz = 10,000,000 kilohertz — 10 × 1,000,000 = 10,000,000 kilohertz

When you need to convert gigahertz to kilohertz

Comparing specifications written for a different market.
Checking a figure quoted in an unfamiliar unit before acting on it.
Converting values consistently across a spreadsheet, report or shopping list.

Common mistakes to avoid

Dividing when you should multiply. Because 1 gigahertz = 1,000,000 kilohertz, the answer should be larger than the number you started with.
Rounding too early. Convert first at full precision, then round the final answer to the precision the task actually needs.

How precise does the answer need to be?

Round only at the end, and only to the precision your task actually needs. The converter above keeps full double precision internally and rounds for display.

How these units are defined

Gigahertz (GHz): One billion cycles per second; CPU and radio frequencies. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
Kilohertz (kHz): One thousand cycles per second. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
