Efficiency is expressed as a factor, like 0.9, or a percentage - the above is equivalent to 90%. An efficiency of 90% means that 90% of the input energy (or a factor of 0.9) is converted into whatever you want to convert it to; the remainder is wasted.

Efficiency is usually expressed as a what?
Efficiency is usually expressed as a ratio of output to input, such as output divided by input. It measures the effectiveness of achieving desired results with minimal waste of resources.
What is the formula of efficiency and power?
Efficiency is calculated as output power divided by input power, usually expressed as a percentage. Power is the rate at which work is done or energy is transferred, calculated as the product of force and velocity.
How is a machines mechanical efficiency is calulated?
Mechanical efficiency of a machine is calculated by dividing the actual output of work by the theoretical output of work, and then multiplying by 100 to express it as a percentage. It is expressed as: efficiency = (Actual output / Theoretical output) * 100%. A higher mechanical efficiency indicates that the machine is operating more effectively with less energy loss.
What is the unit of efficiency?
Efficiency is typically expressed as a percentage, representing the ratio of useful output to input.
What are the units of efficiency?
Efficiency is typically expressed as a percentage, representing the ratio of useful output to input. It can also be expressed as a dimensionless ratio or a specific unit depending on the context, such as miles per gallon for fuel efficiency or lumens per watt for electrical efficiency.
The efficiency of a machine is usually expressed in?
The efficiency of a machine is usually expressed as a percentage. The ideal efficiency of a machine is 100-percent.Another AnswerThere are no units of measurement for efficiency, because you are comparing like with like: output power divided by input power.
Efficiency is usually expressed as a what?
Efficiency is usually expressed as a ratio of output to input, such as output divided by input. It measures the effectiveness of achieving desired results with minimal waste of resources.
What does efficiency mean in science?
The Efficiency of a system is the ratio (Input Energy / Output Energy). The fraction is usually expressed as a percentage.
What do you understand by efficiency of motor or generator?
The efficiency of any machine is the output power divided by the input power, usually expressed as a percentage.
Efficiency can be express mathematically as?
Efficiency = Output/Input. This is usually expressed as a percentage but may be given in the form of a ratio.Another AnswerEfficiency is output power divided by input power, normally expressed as a percentage.

What is the percentage of energy used to do work called?
The percentage of energy used to do work is called energy efficiency. It measures how much of the input energy is converted into useful work output. It is usually expressed as a percentage.
What is a quantity usually expressed as a percentage that measures the ration of work output to work input?
Efficiency is a quantity usually expressed as a percentage that measures the ratio of work output to work input. It shows how much of the work input is successfully converted into useful work output.
What is the comparison between output and input work called?
The comparison between output and input work is called efficiency. It is a measure of how well a system can convert input work into useful output work. Efficiency is usually expressed as a percentage, with 100% being perfect efficiency.
