My CPU is listed as 5.2 GHz boost. A benchmark tool reports it in MHz — what should I see?

You should see 5,200 MHz. Multiply 5.2 × 1,000 = 5,200. Both values describe exactly the same frequency — benchmark tools often read hardware performance counters that return MHz values.

I'm designing an antenna for the 5 GHz Wi-Fi band. The formula I'm using needs frequency in MHz — what do I enter?

Enter 5,000 MHz. Multiply 5 GHz × 1,000 = 5,000 MHz. For a quarter-wave monopole, the length in metres = 300 ÷ (4 × 5,000) ≈ 0.015 m (1.5 cm).

Is my CPU's 5 GHz clock speed related to the 5 GHz Wi-Fi band?

Same unit — different meaning. CPU GHz measures the processor's internal clock oscillation. Wi-Fi GHz is the radio carrier frequency. They happen to use similar numbers but are physically unrelated. A 5 GHz CPU and a 5 GHz Wi-Fi router don't interact because the CPU clock isn't broadcasting radio waves. See [MHz to Hz](/frequency/mhz-to-hz/) for full context.

Why do phone and router specs say 'GHz' but phone teardown engineering articles say 'MHz'?

Consumer marketing favours GHz for readability (one digit instead of four). Engineering documentation uses MHz because most RF component databases, antenna calculators, and spectrum regulatory tables are indexed in MHz. Both are correct; the audience determines which scale is preferred.

Kilohertz → Hertz

Hz = kHz × 1000

Gigahertz → Megahertz

MHz = GHz × 1000

Formula

MHz = GHz × 1,000

Consumer specs, router boxes, and CPU marketing use GHz because the numbers are small and memorable. Antenna engineers, spectrum planners, and RF component datasheets often need MHz — whether for quarter-wave length calculations, selecting filter components, or cross-referencing frequency allocation tables. A router listed as '5 GHz Wi-Fi 6' operates at 5,000 MHz; an antenna cut for that frequency is 300 ÷ (4 × 5,000) = 0.015 m = 1.5 cm. Multiplying GHz by 1,000 gives the MHz value engineers actually work with.

Wi-Fi 2.4 GHz band. Antenna designers and RF engineers reference this as 2,400 MHz when selecting dipole lengths, filter components, and coaxial specifications.

2.4 GHz = 2400 MHz

CPU base clock at 3.6 GHz = 3,600 MHz. Overclocking communities and benchmark databases often report processor speed in MHz for finer granularity.

3.6 GHz = 3600 MHz

Wi-Fi 5 GHz band (802.11ac/Wi-Fi 5). A quarter-wave antenna for this band is 300 ÷ (4 × 5,000) = 0.015 m = 1.5 cm long.

5 GHz = 5000 MHz

Automotive radar at 77 GHz = 77,000 MHz. Radar designers work in MHz for component selection while system specs quote GHz.
