Can I use a regular thermometer to measure my pool's water temperature accurately?

Question

if not than how can I convert the reading so it is accurate to the actual water temperature

Answer 1

Although it's a bit unusal, a regular glass bulb thermometer will work to measure the water temperature in your pool.  If you go to a local pool dealer, they should have an inexpensive pool thermometer you can hang on the side of your pool.

Answer 2

You can use any thermometer that has mercury for a pool and get an accurate temperature.
