A spectrum allocation database lists a satellite band as 10,700,000–12,750,000 kHz. What is that in GHz?

10,700,000 kHz = 10.7 GHz and 12,750,000 kHz = 12.75 GHz. Divide by 1,000,000. This is the Ku-band used for direct broadcast satellite TV.

My old RF signal generator is calibrated in kHz and I need to set it to 2.45 GHz for microwave testing. What do I dial in?

Set it to 2,450,000 kHz. Multiply the GHz target by 1,000,000 to get the kHz value. Double-check the generator's maximum output range before attempting to set frequencies above its rated limit.

Are kHz and GHz ever used together in the same spec sheet?

Yes — especially in wideband receivers and spectrum analyzers that cover ranges from low kHz (audio, AM radio) up to many GHz (microwave, 5G). The same instrument may tune from 9 kHz (0.000009 GHz) to 30 GHz (30,000,000 kHz). Expressing both ends in one unit produces impractical numbers, so spec sheets switch units by frequency range.

I'm cross-referencing an ITU table that shows 76,000,000 kHz. Is that the automotive radar band?

Yes — 76,000,000 kHz = 76 GHz. Automotive collision-avoidance radar operates in the 76–81 GHz range (76,000,000–81,000,000 kHz). See also: MHz to GHz for mid-range conversions.

Key Formulas

Hertz → Kilohertz

kHz = Hz × 0.001

Kilohertz → Hertz

Hz = kHz × 1000

Megahertz → Gigahertz

GHz = MHz × 0.001

Gigahertz → Megahertz

MHz = GHz × 1000

Formula

GHz = kHz ÷ 1,000,000

Legacy spectrum allocation tables and older RF test equipment express frequencies in kHz across the full range — including frequencies now routinely discussed in GHz. When a spectrum database entry shows a band in kHz and you need to compare it to a modern Wi-Fi, cellular, or radar spec stated in GHz, divide by one million. A 2,400,000 kHz entry becomes 2.4 GHz instantly.
