The temperature is a vital consider our day by day lives. It impacts our clothes decisions, our actions, and even our temper. Most of us are accustomed to utilizing a thermometer, however there are literally a number of methods to approximate the temperature with out one. From utilizing your physique as a gauge to observing nature, there are numerous methods that may present an inexpensive estimation of the environmental temperature. Whether or not you are exploring the wilderness or just curious in regards to the temperature in your personal yard, these strategies will empower you with the flexibility to gauge the heat or coolness of your environment with out counting on a thermometer.
Some of the accessible strategies to estimate the temperature is through the use of your physique as a gauge. Take note of how your physique feels. For those who’re feeling scorching and sweaty, the temperature is more likely to be larger. Conversely, when you’re feeling chilly and shivering, the temperature is more likely to be decrease. Whereas this technique isn’t as exact as a thermometer, it may give you a common concept of the temperature vary. Moreover, you’ll be able to observe the conduct of animals and vegetation. Many animals, akin to canine and cats, will search shade or water when it is scorching. Crops can even wilt or droop in extreme warmth. By observing the conduct of residing organisms, you’ll be able to infer the temperature circumstances.
Lastly, there are numerous pure indicators that may present clues in regards to the temperature. The solar’s depth is a dependable indicator. The upper the solar is within the sky, the hotter it’s. Equally, the size of daylight may give you a sign of the season and subsequently the approximate temperature vary. Cloud cowl also can have an effect on the temperature. A transparent, sunny day will typically be hotter than a cloudy day. By combining these observations with the opposite strategies talked about above, you’ll be able to develop a fairly correct estimate of the temperature with out counting on a thermometer. It is essential to notice that these strategies should not foolproof and shouldn’t be used for important purposes, akin to medical analysis or scientific analysis. Nevertheless, for on a regular basis functions, these methods can present a useful approximation of the temperature.
Feeling the Wind
The wind can be utilized to gauge the temperature, as it’s extra noticeable when the temperature is decrease. Typically, the stronger the wind, the colder it’s. Here’s a desk that outlines the connection between wind pace and temperature:
| Wind Velocity | Temperature Vary |
|---|---|
| Calm (0-1 mph) | Above 50°F (10°C) |
| Mild breeze (2-7 mph) | 40-50°F (4-10°C) |
| Mild breeze (8-12 mph) | 30-40°F (-1-4°C) |
| Average breeze (13-18 mph) | 20-30°F (-7–1°C) |
| Recent breeze (19-24 mph) | 10-20°F (-12–7°C) |
| Sturdy breeze (25-31 mph) | Under 10°F (-12°C) |
You will need to observe that that is solely a common guideline, and the precise temperature can range relying on elements akin to humidity and elevation.
Checking the Dew Level
The dew level is the temperature at which the air turns into saturated with water vapor and condensation begins to type. You should use the dew level to estimate the temperature and not using a thermometer.
To test the dew level, you will want a glass of chilly water and a chunk of paper. Fill the glass with chilly water and place the paper on prime of the glass. Wait a couple of minutes and observe the paper. If the paper turns into damp, then the dew level has been reached.
You may as well use a desk to estimate the dew level primarily based on the temperature and the relative humidity.
| Temperature (°C) | Relative Humidity (%) | Dew Level (°C) |
|---|---|---|
| 20 | 50 | 10 |
| 25 | 60 | 15 |
| 30 | 70 | 20 |
Measuring Physique Warmth
1. Brow Contact
Place your hand on the brow of the particular person whose temperature you need to test. If their brow feels heat or scorching, they could have a fever.
2. Armpit Contact
Place your hand contained in the armpit of the particular person whose temperature you need to test. If their armpit feels heat or scorching, they could have a fever.
3. Neck Contact
Place your hand on the again of the particular person’s neck. If their neck feels heat or scorching, they could have a fever.
4. Lips and Tongue Contact
Place your fingers on the particular person’s lips and tongue. If their lips and tongue really feel heat or scorching, they could have a fever.
5. Chest Contact
Place your hand on the particular person’s chest. If their chest feels heat or scorching, they could have a fever.
6. Again Contact
Place your hand on the particular person’s again. If their again feels heat or scorching, they could have a fever.
7. Pores and skin Shade
The pores and skin shade of an individual also can point out their physique temperature. Pale pores and skin can point out a low physique temperature, whereas flushed pores and skin can point out a excessive physique temperature.
| Pores and skin Shade | Physique Temperature |
|---|---|
| Pale | Low |
| Flushed | Excessive |
Studying an Anemometer
An anemometer measures wind pace, and whereas it will not provide you with a direct studying of the temperature, it may be used to estimate the temperature primarily based on the wind chill issue. Wind chill is the体感温度 felt on uncovered pores and skin as a result of mixture of wind and chilly temperatures. The quicker the wind pace, the colder the wind chill will really feel.
To make use of an anemometer to estimate the temperature, you may must know the precise air temperature and the wind pace. You possibly can then use a wind chill chart to find out the体感温度.
Here’s a desk of wind chill elements for various wind speeds and air temperatures:
| Air Temperature (°F) | Wind Velocity (mph) | Wind Chill (°F) |
|---|---|---|
| 30 | 10 | 22 |
| 30 | 20 | 13 |
| 30 | 30 | 5 |
| 20 | 10 | 12 |
| 20 | 20 | 2 |
| 20 | 30 | -8 |
| 10 | 10 | 2 |
| 10 | 20 | -9 |
| 10 | 30 | -19 |
| 0 | 10 | -12 |
| 0 | 20 | -23 |
| 0 | 30 |
To make use of the chart, discover the air temperature within the left-hand column and the wind pace within the prime row. The体感温度 is discovered within the intersection of the 2 rows and columns.
For instance, if the air temperature is 30°F and the wind pace is 20 mph, the体感温度 is 13°F.
It is essential to notice that wind chill is barely a measure of how chilly the wind feels on uncovered pores and skin. It doesn’t mirror the precise air temperature, which may be a lot hotter or colder than the体感温度.
Find out how to Inform the Temperature With out a Thermometer
There are various methods to inform the temperature and not using a thermometer. Some strategies are extra correct than others, however all of them may give you a common concept of the temperature. Listed below are a couple of strategies:
- Use your physique as a information. For those who’re feeling scorching, the temperature might be excessive. For those who’re feeling chilly, the temperature might be low.
