![]() This lets you create a series of data pairs that you’ll then use to develop a calibration curve.Ī two-point calibration of a thermometer using the freezing and boiling points of water would have two data pairs: one from when the thermometer is placed in ice water (32 ☏ or 0 ☌) and one in boiling water (212 ☏ or 100 ☌). To perform a calibration, you compare the readings of a device (like the temperature that a thermometer displays) to known values called standards (like the freezing and boiling points of water). What is a Calibration Curve and How is Excel Useful When Creating One? In this article, we’ll look at how to use Excel to create a chart, plot a linear calibration curve, display the calibration curve’s formula, and then set up simple formulas with the SLOPE and INTERCEPT functions to use the calibration equation in Excel. ![]() ![]() ![]() This can be helpful when you are writing a chemistry lab report or programming a correction factor into a piece of equipment. Excel has built-in features that you can use to display your calibration data and calculate a line-of-best-fit. ![]()
