if you hold a thermometer in each hand, one farenheit and one celsius, and they read the same. What do they read?

one will be in farenheit and the other reading in celsius so, if you want to use the general accepted body temperature, the farenheit one should say 98.6 and the celsius shoud say 37.0 . Is this what you're asking?

There is only one temp they are the same numerical value.

do this:

9/5* (x-32)= 5/9 * x + 32

solve for X

That was what I was leaning toward, I just needed to see if someone else thought the same. Thanks

-40 F or C. You'd better be wearing gloves

How did I get that? Require that
F = (9/5 C + 32)= C
4/5 C = -32
and solve for C (which equals F at that point)

-40 degrees Celsius.

To determine what temperature the Fahrenheit and Celsius thermometers would read if they both show the same value, let's first understand the difference between Fahrenheit and Celsius scales.

The Fahrenheit scale is commonly used in the United States and a few other countries. It divides the temperature range between the freezing point of water and the boiling point of water into 180 equal parts. The freezing point of water on the Fahrenheit scale is 32 degrees, and the boiling point is 212 degrees.

In contrast, the Celsius scale is used in most countries around the world. It divides the temperature range between the freezing point and boiling point of water into 100 equal parts. On the Celsius scale, the freezing point of water is 0 degrees, and the boiling point is 100 degrees.

Now, if you have a Fahrenheit thermometer reading the same temperature as a Celsius thermometer, it means that both thermometers are measuring the same temperature value. This can occur at a specific temperature where the numerical values on both thermometers align.

To find out what temperature that is, we can use the conversion formula between Fahrenheit and Celsius:

°C = (°F - 32) × 5/9

Since we are looking for a temperature where both Celsius and Fahrenheit readings are equal, we can assign the same value to both Fahrenheit (°F) and Celsius (°C) in the formula:

°C = (°F - 32) × 5/9

By substituting °F with °C in the formula, we get:

°C = (°C - 32) × 5/9

Now, we can solve for °C:

°C - °C × 5/9 = 32

Applying some algebraic steps:

(9/9) × °C - (5/9) × °C = 32
(4/9) × °C = 32
°C = 32 × (9/4)
°C = 72

Therefore, if you have a thermometer in each hand, one Fahrenheit and one Celsius, and they both read the same value, they would both read 72 degrees.
