Foot is not a standard instrument of measurement. The length of the foot may vary from person to person. So it can't be used to measure the length of a curved line.
A thread is flexible. It can be bent easily to cover the curved line. It can then be straightened on a scale to measure the length.
Measuring cylinder is used to measure volume of liquids.
Thermometer is used to measure and indicate temperature of any object.
