This metric is defined as the heaviness of an object created by the power of gravity attracting it to the Earth’s center. Measuring weight is present in every aspect of our life: from grocery shopping and healthcare to machine building and construction. People need to know their body mass to take the correct dose of medicine. They need to learn the weight of their parcel to calculate the delivery cost. Sometimes, we don’t even notice how often we deal with this measure, but this doesn’t make it any less weighty.

To define the mass of any container or thing, you should use a specific formula. It allows calculating the weight of any object, provided you know its mass.

Given mass (m) and acceleration due to gravity (g), calculate the weight (W): W=mg

The acceleration due to gravity on Earth equals 9.8 m/s2. When the mass of an object is 30 kilograms, its weight is 294 kg. See it for yourself: W=30*9.8=294 kg.
