List the metric base units for the following:
c. length:
d. distance:
e. mass:
f. temperature:

Meter
meter
gram
Celsius

The base unit for length is meters, which can be compared to yards in the American system.

Generally length and distance mean the same thing, but seeing as they are listed separately here I will assume it means distance as in travel. The metric system used kilometers for distance, which can be compared to American miles.

The mass of objects is measured in grams, which is sort of like ounces in the American system.

Finally, temperature is measured in Celsius, which is Fahrenheit with the American system.
