Welcome back everyone. Another unit for pressure is a bar convert 1 80 M and one millimeter of mercury to bar. So we're going to begin with recalling our conversion factor where 80 M is equivalent to 1.013 bars Next, we want to recall that we have an equivalent of 180 m equal to 760 of mercury. So for our first answer, that's just going to be this conversion factor that we recalled where one A T. M. Is equal to one point oh 13 bars. And now for our second answer, we're going to have to begin with our one millim of mercury given from the prompt and plug in that conversion factor to go from millimeters of mercury to a T. M's. So we have 760 millimeters of mercury equivalent to 1 80 M in the numerator. We can now cancel out millimeters of mercury and now focus on going from a T. M's. Two bars by recalling that as we stated, 1 80 M is equivalent to one point oh 13 bars. So now canceling out a. T. M's were left with bars as our final unit for pressure and plugging everything carefully into our calculator. We're going to yield a result of 1.33 times 10 to the negative third power bars. And so we can confirm that therefore one millim of mercury is equivalent to 1.33 times 10 to the negative third power bars of pressure. And this would be our second final answer. To complete this example. I hope everything our view was clear. If you have any questions, please leave them down below and I'll see everyone in the next practice video.
