Final answer:
Working capital is not usually considered a measure of an entity's liquidity.
Step-by-step explanation:
The measure of liquidity refers to how quickly an entity can use a financial asset to buy a good or service. The current ratio, acid-test ratio, and cash ratio are all commonly used measures of liquidity. However, working capital is not usually considered a direct measure of an entity's liquidity. Working capital is the difference between current assets and current liabilities and provides an indication of an entity's ability to meet its short-term financial obligations.
