What is the standard expression for converting 1 gigahertz to megahertz?

• A. GHz(gigahertz) to MHz(megahertz)
• B. Hz to kHz
• C. MHz to Hz
• D. kHz to Hz

Answer: (A)

Converting between SI prefixes uses powers of ten. A gigahertz is 10^9 hertz and a megahertz is 10^6 hertz, so moving from GHz to MHz reduces the exponent by 3. The standard way to express this conversion is from GHz to MHz, which for 1 unit yields 1 GHz = 1000 MHz. The other options describe different unit pairs or directions, not the GHz to MHz conversion.
