Percent error is calculated by the measured value and the acceped value. For example, if you measure a piece of paper and decide it is 8.45in long, that is your measured value. The package says it is 8.5in long, so it is the accepted value. The formula for percent error is |measured value - accepted value| divided by accepted value ALL times 100.
They are a measurement of distance

A percent error depends on the size of the measurement as well as the error itself. It's very intuitive to think about: If you're measuring a piece of paper and you're off by 4 cm, you'll have problems; if you're measuring the moon, that's nothing. A bigger percent error is a bigger deal to an engineer. You can calculate it the same way as any percentage: Divide the error by the total length of the measurement, then multiply by 100 to convert it from a proportion to a percentage.
Kinetic Energy = 1/2 (mass) (velocity)2Measurement of mass is in error by 3%.Measurement of velocity is in error by 4%.If both are low, then KE is measured as(True KE) x (.97) x (.96)2 = 0.894 TKE = 10.6% low.If both are high, then KE is measured as(True KE) x (1.03) x (1.04)2 = 1.114 TKE = 11.4% high.If one is high and the other low, then the net error is in between these limits.

take reading 4 to 5 times, and take its average this will reduce error
1 inch = 2.54 cm so 4 inches = 10.16 cm
A hand is a measurement for measuring horses. It is equal to 4 inches. There are 2.54 cm in an inch, so (4 in)*(2.54 cm/in) = 10.16 cm
It is 4.50 +/- 0.18
