Efficiency of Energy Transfer Calculator
🌍 Ecology. Use the Efficiency of energy transfer formula to find efficiency, energy at the higher level, energy at the lower level: pick the value you want, type the others, and the answer updates as you go.
Usually about 10 %. The rest goes on respiration, movement, heat and waste.
Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.
What each letter means
| Quantity | Unit |
|---|---|
| Efficiency | % |
| Energy at the higher level | kJ |
| Energy at the lower level | kJ |
Worked example
Find the efficiency when Energy at the higher level = 2000 kJ, Energy at the lower level = 20000 kJ.
Using efficiency = (energy at the higher level)/(energy at the lower level) × 100\%: Efficiency = 10 %.
Frequently asked questions
What is the formula for Efficiency of energy transfer?
efficiency = (energy at the higher level)/(energy at the lower level) × 100\%. Usually about 10 %. The rest goes on respiration, movement, heat and waste.
What do the letters stand for, and what units are used?
Efficiency in %, Energy at the higher level in kJ, Energy at the lower level in kJ.
How do you calculate efficiency?
Put the values into efficiency = (energy at the higher level)/(energy at the lower level) × 100\%. For example, with Energy at the higher level = 2000 kJ, Energy at the lower level = 20000 kJ, efficiency = 10 %.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (efficiency, energy at the higher level, energy at the lower level) and fill in the others: it rearranges the formula for you.
