Mercury thermometres aren't used much, because the mercury inside is poisones,
But the reason that mercury used to be used is because Mercury expands rapidly, conserning the temperature e.g. if it gets hotter, the Mercury expands, so there is more of it. So, when you're measuring the tempurature, you're actually measuring how much mercury is there, therefore telling you what the temperature.
