It is necessary because measuring tools help you measure the length of an object accurately.
A ruler.
The operation in which we measure our desired vertical length and horizontal length with measuring tools (for example;scale,tri-square,vernier calliper, screw gauge,etc. ) and mark that measured vertical length and horizontal length by marking tools for example;scriber, etc. on our metal piece, is called measuring and marking operation.
You need different tools these measurements. For mass you want a scale or balance. You can only use the same tool for length and volume (a ruler, caliper or similar) if the object you are measuring is a well defined solid with known geometric shape. Otherwise you will have to perform a measuring experiment for example put the object you want to determine the volume of in a graduated cylinder, pour a known volume of liquid into the cylinder, read the volume and subtract to determine the object's volume.
The tool that is commonly used with the base units of mass, volume, and length is a measuring instrument or scale. For mass, a balance or scale is used to measure the amount of matter in an object. For volume, a graduated cylinder or measuring cup is typically used to measure the amount of space occupied by a liquid or solid. For length, a ruler or measuring tape is commonly used to measure the distance or size of an object.

Length, Mass, Volume, Density.
There are many instruments (tools) used for measuring. It depends on what you're measuring. A ruler can be used to measure length, a watch to measure time and an anemometer for measuring wind speed.

Tools for measuring lengths are : Screw gauge, vernier calipers,drafter, ruler ,circular scale ,etc . These tools are used for measuring lengths according to their different least counts.
A measuring tool is anything used to determine the magnitude of a physical property of an object in an agreed unit.
