In a lab, i used a micro-caliper to measure the diameter of an indicator; I got [tex]3.681 mm \pm 0.005 mm[/tex]. However, i need the measurement to be in meters and i need to divide the measurement by 2 (as i need the radius, not diameter) for easy calculations. I know how to convert the 3.681 mm to meters, but what about the uncertainty?
radius of indicator:
[tex]3.681 mm * \frac{1 m}{1000 mm} * \frac{1}{2} = 0.00184\underline{0}5 m[/tex]
uncertainty?:
[tex]\pm 0.005 mm * \frac{1 m}{1000 mm} * \frac{1}{2} = 0.00000\underline{2}5 m[/tex]
Is this right?
Thanks in advance.
