How could i know wht's the value of capacitor like o.01 macro farad & others?

First of all the unit is Microfarads not Macro farad (must be a typo). On the capacitor you will find written like 10V 0.01uF. It means the capacitor has maximum voltage tolerance of 10VDC and capacitance of 0.01Microfarads. Also 10nF (nanofarads)=0.01uF.
