How to convert kilohertz to gigahertz
Frequency times wavelength equals c/n, where c is exactly 299792458 m/s. Tables assume vacuum (n = 1). Supply the phase refractive index for your medium and frequency; dispersion and acoustic waves need other models.
Use x for the value in kHz, b for the intermediate value in Hz, and y for the result in GHz.
GHz = kHz × 1000 ÷ 1000000000
Here n = 1 (vacuum). Static examples and tables assume vacuum; changing n in the calculator updates its result only.
Worked examples
10 kHz ≈ 0.00001 GHz
Step 1: (10 × 1000) ≈ 10000 Hz.
Step 2: 10000 ÷ 1000000000 ≈ 0.00001 GHz.20 kHz ≈ 0.00002 GHz
Step 1: (20 × 1000) ≈ 20000 Hz.
Step 2: 20000 ÷ 1000000000 ≈ 0.00002 GHz.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Kilohertz
Kilohertz (kHz) measures frequency wavelength under the conventions above. The base value in Hz is (x × 1000), where x is the numerical value in kHz. Factors shown here are rounded for display; calculations use the stored factor.
About Gigahertz
Gigahertz (GHz) measures frequency wavelength under the conventions above. The base value in Hz is (x × 1000000000), where x is the numerical value in GHz. Factors shown here are rounded for display; calculations use the stored factor.
