A home barometer reads a pressure of 0.986 bar. What is this pressure in kPa?

A. 986 kPa
B. 98.6 kPa
C. 0.999 kPa
D. 0.973 kPa
E. 740 kPa

Answer :

The pressure of 0.986 bar is equivalent to 98.6 kPa.

The pressure of 0.986 bar can be converted to kPa by multiplying it by 100.

Here's how you can convert it step by step:

1. Multiply the pressure in bar (0.986) by 100 to convert it to kPa:
0.986 bar * 100 = 98.6 kPa

So, the correct answer is 98.6 kPa.

To convert bar to kilopascal (kPa), you need to multiply the value in bar by 100. In this case, the home barometer reads a pressure of 0.986 bar. To convert this to kPa, you multiply 0.986 by 100, which gives you 98.6 kPa.

Therefore, the pressure reading of 0.986 bar is equal to 98.6 kPa. The conversion factor of 100 is used because there are 100 kilopascals in 1 bar. This conversion is commonly used in scientific and engineering fields to express pressure in different units.

In conclusion, a pressure reading of 0.986 bar is equal to 98.6 kPa when converted.
