Percentages space sometimes much better at expressing various quantities 보다 decimal fractions in chemistry or physics. For example, that is lot convenient come say that percentage concentration that a details substance is 15.7% than that there space 18.66 grams of substance in 118.66 grams of equipment (like in an instance in percent concentration calculator). One more example is effectiveness (or that is special case - Carnot efficiency). Is it better to say that a auto engine works v an efficiency of 20% or the it produce an power output the 0.2 kWh from the input energy of 1 kWh? What do you think?
