How does a terahertz camera (1 THz) compare in frequency to my WiFi (2.4 GHz)?

2.4 GHz = 2,400 MHz. A 1 THz = 1,000,000 MHz. Divide: 1,000,000 ÷ 2,400 = 416.7. Terahertz is 416× higher frequency. Wavelength scales inversely: WiFi is centimeters; terahertz is tens of micrometers. See [MHz to GHz]({/frequency/mhz-to-ghz/}) for the WiFi scale breakdown.

A terahertz spectroscopy lab publishes results at 0.5 THz and 2 THz. What's the MHz range?

0.5 THz = 500,000 MHz, 2 THz = 2,000,000 MHz. The lab operates from 500 kMHz to 2,000 kMHz—a range spanning far-infrared vibrational signatures of nearly all materials.

Why do RF engineers care about terahertz if it's so far beyond MHz frequencies?

6G and beyond-wireless research is pushing toward terahertz for massive bandwidth. Millimeter-wave 5G (28–73 GHz) proved the feasibility; terahertz extends that—lower latency, higher data rates. But the challenges are immense: higher atmospheric absorption, new antenna designs, and device physics differs drastically from MHz-scale RF circuits.

A research institute is building terahertz communication at 0.3 THz. How many MHz is that?

0.3 THz = 300,000 MHz = 300 GHz. This is in the THz band but at the low end of spectroscopy ranges. Wavelength = 1 mm—useful for wireless communication with line-of-sight links and compact antennas, though rain and oxygen absorption are significant challenges.

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

MHz = THz × 1,000,000

Megahertz measures radio frequencies—FM stations at 88–108 MHz, WiFi at 2,400 MHz, cellular bands, and RF circuits. Terahertz sits a million times higher, in the far-infrared region where molecular and crystal properties reveal themselves through spectroscopy. Converting THz to MHz helps researchers and engineers contextualize where terahertz research stands relative to conventional RF systems. A 1 THz terahertz sensor equals 1 million MHz—far beyond any practical RF application, yet still much lower energy than visible light.
