What are the equipment that is used to measure length, time, temperature, current and mass?

Answer 1

Gee that is a good one
1- Length - yard stick, meter stick, a ruler a measuring tape...
2. Time- A watch would do, an atomic clock is even better
3. Temperature- Thermometer (fluid expansion, lineal expansion, infrared detection, ...)
4. Current - (I presume electric current) an ammeter or in general a galvanometer.
5. Mass - Mass is best measured by comparison to other masses by employing balances of forces like in a spring or torsion scales...

This just scrapes the surface ;-)
