What type of pressure does torr measure?

Torr measures low to moderate vacuum pressures and is used in vacuum systems and gauges.

Why convert torr to micropascal?

Converting torr to micropascal allows expressing low vacuum pressures in units suited for very small pressure variations such as acoustic measurements.

Is micropascal used for general pressure measurement?

Micropascal is mainly used to quantify very small absolute pressures or sound pressure levels, not for general high-pressure measurements.
