Frequently Asked Questions
What is 1 GHz in MHz?▾
1 GHz equals 1,000 MHz. Modern processors run at 3-5 GHz (3,000-5,000 MHz). Wi-Fi operates at 2.4 GHz and 5 GHz bands.
What frequencies can humans hear?▾
Humans can typically hear frequencies between 20 Hz and 20,000 Hz (20 kHz). Bass notes are around 60-250 Hz, speech is around 300-3,000 Hz, and high-pitched sounds can reach 15,000+ Hz.
What is RPM in frequency terms?▾
RPM (revolutions per minute) can be converted to Hz by dividing by 60. For example, a 3,600 RPM motor runs at 60 Hz — matching the standard US AC power frequency.
