What is the metric equivalent of 1 liter in deciliters?

• A. 1 dL
• B. 10 dL
• C. 100 dL
• D. 1000 dL

Answer: (B)

To determine the metric equivalent of 1 liter in deciliters, it's important to understand the relationship between these two units of measurement for volume.

1 liter is defined as equivalent to 10 deciliters. This relationship is based on the metric system, where the prefix “deci-” indicates one-tenth of a unit. Therefore, 1 deciliter is equal to 0.1 liters. Consequently, when you multiply 1 liter by the conversion factor of deciliters, you can calculate the equivalent amount in deciliters.

Since there are 10 deciliters in a liter, the conversion is straightforward: 1 liter × 10 dL/L = 10 dL. This clearly confirms that the metric equivalent of 1 liter is indeed 10 deciliters. Thus, the correct choice reflects this relationship accurately.
