Difference between Temperature and Wind Chill

Difference between Temperature and Wind Chill

Most people think of temperature and wind chill as the same thing, but they are actually two different measurements. Temperature is how warm or cold something is, while wind-chill measures how the wind affects our perception of temperature. In other words, wind chill tells us how cold we feel based on the combination of temperature and wind speed. For example, if it’s 30 degrees Fahrenheit outside and the wind is blowing at 20 mph, then the wind chill would be minus 11 degrees Fahrenheit. Knowing the difference between temperature and wind chill can help you better prepare for extreme weather conditions.

What is Temperature?

  • Temperature is a measure of the average kinetic energy of the particles in a system. The SI unit for temperature is the Kelvin (K), which is defined by setting the Boltzmann constant, k, equal to 1. Temperature is often measured in units of degrees Celsius (°C), and sometimes in Fahrenheit (°F). The Rankine (°R) scale is also occasionally used.
  • The Kelvin scale is absolute, meaning that 0 K is the lowest possible temperature. The Celsius and Fahrenheit scales are relative, with 0 °C and 32 °F corresponding to the freezing point of water, respectively. Temperature can be measured using a variety of devices, such as thermometers, bolometers, and pyrometers.
  • It can also be calculated from other properties of matter, such as pressure or entropy. Temperature plays an important role in many fields, including physics, chemistry, engineering, and meteorology. High temperatures can lead to increased chemical reactions, while low temperatures can cause materials to become brittle.
  • Temperature also affects the behavior of sound waves and electromagnetic radiation. In addition, temperature gradients can drive convection and create winds. Thus, the understanding temperature is crucial for understanding many phenomena in the world around us.

What is Wind Chill?

  • The wind chill is the apparent temperature one feels when outdoors in cold weather due to the combination of wind and low temperature. The wind chill temperature is always lower than the actual air temperature and is affected by the wind speed and air temperature. For example, If the air temperature is 30 degrees Fahrenheit and the wind speed is 15 mph, the wind chill would be 26 degrees Fahrenheit.
  • The National Weather Service uses the formula below to calculate the wind chill ˚F = 35.74 + 0.6215T – 35.75V0.16 + 0.4275TV0.16 where T = air temperature in ˚F and V = wind speed in mph. The wind chill index only applies to temperatures at or below 50 ˚F and wind speeds above 3 mph.
  • When either of those two conditions is not met, the Wind Chill will be equal to the air temperature. The existence of a measurable “wind-chill factor” was first proposed by Dr. Paul Siple while on explorer Ernest Shackleton’s Antarctica expedition in 1939 as a way to help predict when frostbite might occur.

Difference between Temperature and Wind Chill

Temperature is the measure of how hot or cold something is. The colder something is, the more heat it will absorb from its surroundings to try and become warm. The wind chill is a measure of how cold the air feels on your skin. It is affected by both the temperature and the wind speed. The faster the wind is blowing, the more heat it will remove from your skin. As a result, you will feel colder in high wind conditions than you would if the wind was not blowing. The wind chill is a useful measure for determining how cold it feels outside and whether you need to dress warmly. However, it is important to remember that the wind chill does not affect how hot or cold something actually is, only how it feels.


The wind chill factor is important to be aware of because it can impact how cold you feel. It’s especially important to be aware of the wind chill when spending time outdoors in the winter. Make sure to dress appropriately for the weather and take precautions against frostbite and hypothermia.
