Question

A healthy dog has a temperature ranging from \(37.8^{\circ} \mathrm{C}\) to \(39.2^{\circ} \mathrm{C}\). Is a dog with a temperature of \(103.5{ }^{\circ} \mathrm{F}\) within the normal range?

Short answer

After converting \(103.5^\circ \text{F}\) to Celsius, compare the result with the normal range (\(37.8^\circ \text{C} \) to \(39.2^\circ \text{C}\)).

Step-by-step solution

Convert Fahrenheit to Celsius

To determine if the dog's temperature is within the normal range, we first need to convert the temperature from Fahrenheit to Celsius using the conversion formula: \( T_{\text{Celsius}} = \frac{5}{9}(T_{\text{Fahrenheit}} - 32) \) where \( T_{\text{Fahrenheit}} \) is the temperature in Fahrenheit. Plug in the dog's temperature of \( 103.5^\circ \text{F} \) into the formula to get the temperature in Celsius.

Perform the Conversion

Using the conversion formula from Step 1, calculate the Celsius temperature: \( T_{\text{Celsius}} = \frac{5}{9}(103.5 - 32) \) and simplify.

Compare with Normal Range

Once we have the Celsius temperature, we compare it to the normal range for a healthy dog, which is \(37.8^\circ \text{C} \) to \(39.2^\circ \text{C}\). If the converted temperature lies within this interval, then the dog's temperature is within the normal range.

Key concepts

Understanding Fahrenheit to Celsius Conversion

Familiarizing yourself with the process of converting temperatures from Fahrenheit to Celsius is essential in various fields—including science, cooking, and even pet care! The key to making this conversion is recognizing the fundamental differences between these two temperature scales. While Fahrenheit is primarily used in the United States, Celsius is commonly utilized in other countries and in scientific contexts.

To convert Fahrenheit to Celsius, you subtract 32 from the Fahrenheit temperature, multiply by 5, and then divide by 9. Why these numbers? The constants in the formula represent the scale differences between freezing and boiling points of water on each scale—32 degrees Fahrenheit is the freezing point of water, which corresponds to 0 degrees Celsius, and 212 degrees Fahrenheit is the boiling point, equivalent to 100 degrees Celsius.

It's important to grasp this conceptually because temperature conversions are not simply shifting numbers; they involve understanding the scale and context of what these temperatures represent. By mastering this skill, you will be able to seamlessly interpret weather reports, recipes, and scientific data across different regions and units of measure.

Normal Body Temperature in Dogs

The well-being of our canine companions is of paramount importance to pet owners, and knowing the normal body temperature of dogs is crucial. Dogs generally have a warmer body temperature range compared to humans. While a normal human body temperature hovers around 98.6°F, or 37°C, dogs range between 101.5°F (38.6°C) and 102.5°F (39.2°C).

The normal range mentioned is crucial for understanding canine health. A temperature outside this range might indicate illness or infection, necessitating veterinary attention. To identify potential health concerns in dogs, we often need to convert their body temperature from Fahrenheit to Celsius, especially in regions where the Celsius scale is commonly used. If you own a thermometer that reads in Fahrenheit, being adept at this conversion can be incredibly helpful.

It's imperative for pet owners to recognize the signs of a fever in dogs, such as lethargy, shivering, or a hot and dry nose. If any abnormal signs are present, measuring your dog's temperature and converting it to the appropriate scale can assist in deciding the next steps to take for their care.

Using the Temperature Conversion Formula

The temperature conversion formula is a mathematical tool that allows us to seamlessly convert temperatures from one scale to another—in this case, from Fahrenheit to Celsius or vice versa. This formula is based on the relationship between the two scales and involves a simple algebraic equation: \( T_{\text{Celsius}} = \frac{5}{9}(T_{\text{Fahrenheit}} - 32) \).

The beauty of this formula lies in its widespread applications beyond academic exercises. Whether you're adjusting cooking temperatures in recipes, interpreting climate data, or even ensuring a pet's health, knowing how to manipulate the formula to fit your needs is immensely useful.

Let's walk through a typical conversion calculation: To convert a temperature of 103.5°F to Celsius, you first subtract 32 from 103.5, giving you 71.5. Then, multiply 71.5 by 5, yielding 357.5, and finally, divide by 9, resulting in about 39.7°C. Understanding and employing this formula confidently can make these everyday conversions a simple task, allowing for quick and accurate interpretation of temperatures in diverse contexts.
