When the prefix 'milli-' is used, what does it mean in terms of multiplication?

• A. Multiply by 0.1
• B. Multiply by 0.01
• C. Multiply by 0.001
• D. Multiply by 1

Answer: (C)

The prefix 'milli-' is derived from Latin and denotes a factor of one thousandth, which is mathematically represented as 0.001. This means that when you see a measurement that uses the prefix 'milli-', such as millimeter or milliwatt, it indicates that the quantity is one thousandth of the base unit (meter or watt, respectively). For example, one millimeter is equal to one thousandth of a meter. Understanding this prefix is essential in fields such as electrical work and engineering, where precise measurements are critical.
