conversion

Examples of conversion in the following topics:

• Converting Units

  • Converting between units can be done through the use of conversion factors or specific conversion formulas.
  • Conversion of units is the conversion of different units of measurement for the same quantity, typically using conversion factors.
  • There are several ways to approach doing conversions.
  • Each conversion factor is equivalent to the value of one.

• Dimensional Analysis

  • For common conversions, you might already know how to convert off the top of your head.
  • But for less common ones, it is helpful to know how to find the conversion factor:
  • You can then use ratios to figure out the conversion:

• Energy Transformations

  • When analyzing energy transformations, it is important to consider the efficiency of conversion.
  • The efficiency of conversions describes the ratio between the useful output and input of an energy conversion machine.
  • Other energy transformations occur with a much lower efficiency of conversion.
  • The process of photosynthesis is able to transform the light energy of the sun into chemical energy that can be used by a plant with an efficiency of conversion of a mere 6%.

• Heat Engines

  • In thermodynamics, a heat engine is a system that performs the conversion of heat or thermal energy to mechanical work.
  • In thermodynamics, a heat engine is a system that performs the conversion of heat or thermal energy to mechanical work .
  • The second law, in its second form, clearly states that such engines cannot have perfect conversion of heat transfer into work done.
  • In the conversion of energy to work, we are always faced with the problem of getting less out than we put in.

• Human Metabolism

  • The 1st law of thermodynamics explains human metabolism: the conversion of food into energy that is used by the body to perform activities.
  • Metabolism in humans is the conversion of food into energy, which is then used by the body to perform activities.
  • This process is the intake of one form of energy—light—by plants and its conversion to chemical potential energy.

• Radiation from Food

  • X-rays are generated by colliding accelerated electrons with a dense material (the target), such as tantalum or tungsten, in a process known as bremsstrahlung-conversion.
  • They also permit dose uniformity, but these systems generally have low energetic efficiency during the conversion of electron energy to photon radiation, so they require much more electrical energy than other systems.

• Conservation of Nucleon Number and Other Laws

  • It is well understood that the tremendous amounts of energy released by nuclear fission and fusion can be attributed to the conversion of mass to energy.
  • However, the mass that is converted to energy is rather small compared to any sample, and never includes the conversion of a proton or neutron to energy.

• Humans: Work, Energy, and Power

  • Our own bodies, like all living organisms, are energy conversion machines.
  • The total energy conversion rate of a person at rest is called the basal metabolic rate (BMR) and is divided among various systems in the body.
