What unit is used for mass?
The SI unit of mass is the kilogram (kg). In science and technology, the weight of a body in a particular reference frame is defined as the force that gives the body an acceleration equal to the local acceleration of free fall in that reference frame.
What is my height in metric?
To convert your height to its metric equivalent, start by calculating your height in inches only. A person who’s 5 feet, 6 inches tall is 66 inches. One inch equals 2.54 centimeters (cm). So, to make the conversion, simply multiply your height in inches by 2.54 to get your height in centimeters.
