Most ceramic capacitors use a numbering scheme similar to the resistor color code. Usually, three numbers are given.
The first two numbers are significant figures, and the third is the base 10 multiplier, or number of zeroes to add onto the end.
With ceramic capacitors, the value you get is typically assumed to be in picofarads (pF, 10-12 Farads). For much larger capacitors, the value is sometimes given in micro-Farads (uF, 10-6 Farads).
For example, for a capacitor marked "154":
1: First sig. fig
5: Second sig. fig
4: multiply by 104 (add 4 zeroes)
Result: 150,000 pF
Now, you can divide by one million to get an answer in uF, if that is more comfortable for you to work with:
150,000 pF = 0.15 uF
Therefore, a capacitor marked 154 has a value of 0.15 uF.
This should get you started reading ceramic capacitor values. For more detail, see the "coding" section of the wikipedia article on ceramic capacitors.

What is an unpolarized capacitor?
A capacitor that does not have a designated + and - side. Electrolytic capacitors are usually polarized. Ceramic capacitors are not.
How do capacitors classified?
capacitors are classified on the basis of dielectric material used inside it. For example the electrolytic capacitor consist electrolyte as dielectric mica capacitor consist mica as dielectric between plates and ceramic capacitor consist ceramic as dielectric.
Can I check the capacitor value by using analog or multimeter?
You can see if the capacitor charges and discharges with an ohmmeter. You can check the value of the capacitor if the multimeter has the facility. With an ESR meter you can establish the value of the capacitor while in circuit.

What does a ceramic capacitor do?
A ceramic capacitor is an electronic component that stores and releases electrical energy in a circuit. It is commonly used to filter out noise and stabilize voltage in electronic devices. Ceramic capacitors are known for their stability, reliability, and high-frequency performance.
How to test an AC capacitor with a digital multimeter?
To test an AC capacitor with a digital multimeter, set the multimeter to the capacitance setting. Disconnect the capacitor from the circuit and discharge it. Connect the multimeter leads to the capacitor terminals and read the capacitance value displayed on the multimeter screen. Compare this value to the rated capacitance of the capacitor to determine if it is functioning properly.
What is use of decoupling capacitor?
to protect a circuit from damaging
A capacitor with lowest leakage is Paper or Ceramic or Polyester or Mica?
mica
How can I use a digital multimeter to test a start capacitor?
To test a start capacitor using a digital multimeter, set the multimeter to the capacitance measurement mode. Disconnect the capacitor from the circuit and discharge it. Connect the multimeter leads to the capacitor terminals and read the capacitance value displayed on the multimeter. Compare this value to the rated capacitance of the capacitor to determine if it is functioning properly.
How do you crush a ceramic capacitor for FTIR analysis?
Crushing a ceramic capacitor for FTIR analysis can be done by placing the capacitor in a mortar and pestle and grinding it into a fine powder. Ensure that the ceramic material is completely broken down to achieve a homogeneous sample for FTIR analysis. Wear appropriate protective gear to prevent inhalation of particles during the crushing process.
