You measure the sides of the cube to find the volume and weigh it to find its mass. This will convert the answer into percent form. If you need to know positive or negative error, this is done by dropping the absolute value brackets in the formula. In most cases, absolute error is fine. Just add the percentage symbol to the answer and you're done.

MESSAGES LOG IN Log in via Log In Remember me Forgot password? Negative Percent Error The formula for calculating percentage error is simple:[1]'[(|Exact Value-Approximate Value|)/Exact Value] x 100 The approximate value is the estimated value, and the exact value is the real value.

For example, if you know a length is 3.535 m + 0.004 m, then 0.004 m is an absolute error. Percent Error Calculator In plain English: The absolute error is the difference between the measured value and the actual value. (The absolute error will have the same unit label as the measured quantity.) Relative Apply correct techniques when using the measuring instrument and reading the value measured. For this reason, it is more useful to express error as a relative error.
