Comment une fréquence en mégahertz peutelle être exprimée en gigahertz?
- AEn la multipliant par 1 000 000
- BEn la divisant par 1 000
- CEn la multipliant par 1 000
- DEn la divisant par 1 000 000
Correct answer: B — En la divisant par 1 000. Question tirée de la banque officielle d'ISDE.
Why
To change a frequency from megahertz to gigahertz, you must divide by 1 000 because a gigahertz is a larger unit containing one thousand megahertz. The full explanation — and one for every question — is in Pro.
