If you divide by seven instead of multiplying by seven, you are off by a factor of 49. Example, to calculate the percentage: 100 x 7 = 700, 100 / 7 = 14.29. The percentage error is about 98%.

What is the reason for percent error?

What is the difference between an error as a percentage of full scale or an error as a percentage of reading?

Error as a percentage of full scale is established by multiplying the error percentage by the full scale flow. The less you flow through the device the less accurate the reading will be. For that reason, you don't want to get a larger device than you need. Devices with error expressed as a percentage of full scale are most accurate when flowing at full scale.Error expressed as a percentage of reading expresses error as a percentage of what the device is actually flowing. Simply, if a instrument's accuracy is rated to +/-1% of reading an instrument will be accurate to +/-1% of whatever the instrument is flowing. At 100SLPM the instrument will be accurate to within +/-1SLPM, and at 10SLPM of flow the unit will be accurate to within +/-.1SLPM.

How do you calculate percentage error for equipment?

Look on the equipment for where it says the plus or minus figure for accuracy (for a burette it is usually + and _ 0.1cm3) divide this by the amount you measured , times 100 to make it a percentage. ---- ---- Percentage Error = Maximum Error / Measured Value X 100 For example.Maximum Error for the following apparatus are:Balance = +/- 0.01Pippette = +/- 0.1 And the Measured value for each are:Balance = 0.15Pippette = 25 Then...the percentage error is:Balance percentage error = 0.01 / 0.15 X 100 = 66.66%Pippette percentage error = 0.1 / 25 X 100 = 0.3% You can now also work out your maximum total error.Maximum total Percentage error = Balance Percentage error + Pippette Percentage errorMaximum total percentage error = 66.66 + 0.4 = 67.06%
