How do you measure room temperature using thermometer?

-- Bring thermometer into room.

-- Wave it around in the air of the room for a minute or two.

-- Do not hold the thermometer in your hand or breathe on it.

-- Wait a while for the room temperature to get through the thermometer glass.

-- Look through the glass at the sliver of liquid inside the thermometer. Find the

end of the liquid, and see what number is marked on the glass at the same level.

That number is your room temperature.
