How many volts are equal to one kilovolt?

  1. Ten volts

  2. One hundred volts

  3. One thousand volts

  4. One million volts

The correct answer is: One thousand volts

One kilovolt is equal to one thousand volts because the prefix "kilo-" in the International System of Units (SI) denotes a factor of one thousand. This standardized naming convention helps in easily communicating measurements across various fields, including electrical engineering. The conversion is straightforward: 1 kV (kilovolt) = 1,000 V (volts). Understanding these prefixes is crucial for working with electrical systems and calculations, as it allows for more efficient handling of large numbers, simplifying both numerical expressions and problem-solving.
