Force is mass accelerated over time. One newton is the force required to accelerate 1 kg of mass 1 meter per second squared.

Gram, pound, and ton refer to mass, while the pint is an English unit of volume.

The meter measures length. When you multiple units of distance, you get surface area.

When you cube a distance, you get volume. Cubic centimeters is an example. Another common volume unit is the liter or milliliter (SI) and quart or pint (English). The erg is a unit of energy, while nanometers measures length and milligrams measures mass.

If you don't remember any other answers from this quiz, know this one. The kilometer is a base unit of length or distance in the metric system.

Ohm and mho are units of resistance. A mho (if you had not noticed) is ohm spelled backwards and is the reciprocal of an ohm.

The Pascal is the metric unit of pressure. It's newtons per square meter or kilograms per meter second squared. The unit is capitalized because it's named for a person.

Kelvin (which is not reported in degrees) and degrees Fahrenheit and Celsius are units of temperature. The BTU is a unit of work.

Watts are power. On a light bulb, for example, they indicate how much power the bulb will draw. So, you shouldn't put a high powered bulb in a socket only built to withstand low power.

Nice try! You had trouble with the units of measurement, but now you know more than you did before you took the quiz. Improve your understanding with a quick review of common metric or SI units.

Good job! You knew some of the basic units of measurement, but there were a few that were unfamiliar to you. Even if you don't know the English unit, make sure you understand the base units used in the metric system.

If you're up for another quiz, see whether you can do metric to metric unit conversions.

Great work! You're comfortable with metric and English units of measurement. From here, make sure you're comfortable with the metric base units and how to convert between English and metric units.
