Convert Hertz to Revolutions per Second

📜 Origins

Heinrich Hertz proved electromagnetic waves exist in 1887. The unit "hertz" was adopted in 1960 in his honor.

⚡ Historical Highlight

The "War of Currents" between Edison (DC) and Tesla (AC) was partly about frequency. Tesla's 60 Hz won in the US, 50 Hz in Europe.

🎯 Fun Facts

• •Middle C note on a piano vibrates at 261.63 Hz - your ear detects these vibrations as sound!
• •Dogs can hear up to 45,000 Hz, while humans max out around 20,000 Hz (less as we age).
• •Wi-Fi operates at 2.4 GHz or 5 GHz - that's billions of cycles per second!

🏛️ Archaeological Discovery

Pythagoras (500 BCE) discovered musical harmony ratios - a string half as long vibrates at double the frequency.

🚀 Modern Applications

Modern CPUs run at 3-5 GHz. Quantum computers will use frequencies in terahertz range for even faster computing.
