what tools do we use to measure mass what units do we use when measuring

To measure mass, we use a variety of tools depending on the scale of the object being measured. Here are some commonly used tools:

1. Balance scale: A balance scale compares the unknown mass of an object with standardized masses to determine its mass accurately. It is commonly used for measuring larger masses, such as in lab experiments.

2. Triple beam balance: A triple beam balance is a commonly used tool in schools and labs. It has three sliding beams, each with a set of weights that can be adjusted to measure the mass of an object.

3. Digital scale: Digital scales use electronic components to measure mass accurately. They are commonly found in households and can measure both small and large masses.

The units used to measure mass depend on the system of measurement being used. The two most widely used systems are the metric system (SI units) and the Imperial system. Here are the units for measuring mass in both systems:

In the metric system (SI units):
- Gram (g): This is the basic unit for measuring mass. It is commonly used for small objects or substances.
- Kilogram (kg): This is the larger unit of mass commonly used for heavier objects, such as humans, vehicles, or larger quantities of substances.

In the Imperial system:
- Ounce (oz): This unit is commonly used for measuring smaller masses, such as food ingredients or precious metals.
- Pound (lb): This is the larger unit of mass commonly used for larger objects or bodies, such as people, animals, or heavier items.

It's important to note that the metric system is widely used and considered standard in most scientific fields globally.
