+### Lab #1 - Measurements of machining precision and accuracy
+
+**Outline and figures at beginning of following lab**
+
+All measurements have traceable standards. There are seven base units in SI -               
+meter (length), second (time), Mole (amount of substance), Ampere (electric                 
+current), Kelvin (temperature), Candela (Luminous intensity), and kilogram                  
+(mass) [1](https://www.nist.gov/pml/weights-and-measures/metric-si/si-units).               
+Any measurement you make should have some method to check against a reference.              
+In this lab, we will use calipers that measure dimensions i.e.  meter\*10$^{-3}$            
+(length). Calipers can always be verified to work with gage blocks.
