Cortana weather forecast in Celsius. Cortana learns as it goes. What worked well for me was asking for weather in Celsius in my questions and after a while ( I think 7 - 9 responses) she started to provide the weather in Celsius by default. Other users reported that they asked her to show temperature in Celcius by default and she made it default.
A respiratory profile consists of measurements of different volumes within your lungs. How much air you breathe is determined by your activity level. The amount of air you inhale in a normal breath while at rest is called your tidal volume (TV). Your body needs more oxygen when performing strenuous work or exercise tasks. The inspiratory reserve volume (IRV) is the maximum additional lung volume
Vital lung capacity is the total amount of air a person can exhale after inhalation. It depends on the age of the person, with young people having a greater lung capacity, as well as the amount of cardiovascular exercise they get, lung health and height.
