Capacitor manufacturers generally give the value of capacitor on capacitor but, in some cases there may be not enough space. In that case, they use simple notation. If it is 2 digits number then no issues. You can say the value seen is the value on capacitor. But if it has 3 digits then the first two digit you take as is and remaining last digit is the number of zeros following that first two digits. See table below;
