Document Summary
Length: 1 inch = 2. 54 cm, range of length. 10^30 meters (distance to the boundary of the known universe) Volume: 20 drops of water = 1 cubic centimeter = 1 ml, range of volume. Mass and weight: mass the amount of matter in an object leads to gravitational attraction between objects and gives rise to weight. Anything that occupies space (volume) and has a mass: a scale would be affected by gravity, but not a balance. The mass of the two objects would remain the same. The gravitational pull on the objects will change depending on how strong the force is in that place: temperature, celsius. 100-unit difference between freezing and boiling: fahrenheit, kelvin. 180-unit difference between freezing and boiling no negative numbers on the scale lowest possible value is a 0 k (absolute zero) Celsius= kelvin 273. 15: celsius and fahrenheit.
