Question

which unit is commonly used in both the metric and the us systems of units?

a. liter

b. minute

c. pound

d. gram

Explanation:

• Liter (A): The liter is a metric unit for volume. It is not commonly used in the US customary system (the US customary system uses units like gallons, quarts, pints, and cups for volume).
• Minute (B): Time is a universal concept. The minute is a unit of time. In the metric system, time can be measured in seconds (with prefixes like milli - (ms), micro - (μs) etc.), but minutes (where \(1\) minute \(= 60\) seconds) are also used. In the US system, minutes are a common unit of time (e.g., when telling time, in cooking recipes that mention time, etc.).
• Pound (C): The pound is a unit of mass/weight in the US customary system. The metric system uses grams (with prefixes like kilo - (kg), milli - (mg) etc.) as the base unit for mass/weight.
• Gram (D): The gram is a base unit of mass in the metric system. It is not a common unit in the US customary system (the US uses pounds and ounces for mass/weight).

Answer:

B. minute
