# What is Water Equivalent? | Definition, Symbol, Units, Formula – Thermometry and Calorimetry

Water Equivalent Definition:
It is the quantity of water whose thermal capacity is same as the heat capacity of the body. Water equivalent is generally used in comparison of a water quantity.

We are giving a detailed and clear sheet on all Physics Notes that are very useful to understand the Basic Physics Concepts.

## What is Water Equivalent? | Definition, Symbol, Units, Formula – Thermometry and Calorimetry

Water Equivalent Symbol:
It is denoted by W.

W = ms = heat capacity of the body.

Water Equivalent Unit:
SI unit for water is kg
Its expressed in the unit gram.

Water Equivalent Dimensional Formula:
Dimensional formula is [M1L0T0].

Thermometry and Calorimetry:
The thermometer is a device used to check the temperature of an object. This branch of measurement of the temperature of a substance is called thermometry. It is measured in degrees or Fahrenheit, usually.

Calorimetry also means the measurement of heat but in joules. It states the amount of heat lost by the body is the amount of heat gained by its surrounding.
