Scientist use the metric system. All science in the metric system.
A scientist is doing an experiment to see how a high-protein low-carbohydrate diet affects the body mass of mice.

The SI unit for mass measurement is the kilogram (kg).
when one scientist tells another scientist that something is certain length, that measurement should mean the some thing to both of them.
Weight is not a physical property of an object, it is an effect, which varies from place to place. A given object will have the same mass no matter whether it is on the Earth, or on Mars, or somewhere in between.

They use a tri beam scale.
Scientists use a scale or a balance to measure mass. These tools can provide an accurate measurement of an object's mass in grams or kilograms.
a meter
Mass!
We use grams (g) as the unit of measurement to measure mass on a triple beam balance.
