We would use a ruler to measure the length of a rock. Then, when we were ready to
write down the result of the measurement, or tell someone else about it, we would pick
the best unit of length to use. The best one would be the unit that results in the most
convenient number.
For a tiny rock, the "millimeter" might be best.
For a medium rock, the "centimeter" might be best.
For a large rock, the "meter" might be best.
A really humongous rock, such as the moon, might warrant the use of the "kilometer".
110 centimeters right? and u want it in mm right? well, you would times by 10. so the answer would be 1100mm. I ROCK Giggle

To determine the length of a rock, you can use a ruler or a tape measure. Simply place the rock on a flat surface, align the ruler next to it, and measure the distance from one end to the other in a straight line.
Cubic units, such as cubic centimeters (cm³) or cubic inches (in³), are commonly used to measure the volume of a solid object like a rock. Volume represents the amount of space occupied by the rock.
You would measure the length width and heighth. Then you would multiply them all together. <><><> A better means would be to have a container that the rock will fit in, and fill it full of water. Place the rock in the container, which will overflow. Then remove the rock, and measure the volume of water you have to pour into the container to make it full again. The volume of the water will equal the volume that was displaced by the rock.
Conglomerate would be formed by the compaction and cementation of particles 1.5 centimeters in diameter. Conglomerate is a coarse-grained sedimentary rock composed of rounded fragments cemented together.
You would determine the volume of water it displaces and measure it.

"Centimeter" is a unit of length or distance, as of a finger, a piece of rope, or your drive to work. "Pound" is a unit of force, as the weight of a rock, or the thrust of a rocket engine. The two units have different dimensions and are used to measure different types of quantities. Neither one can be converted into the other one ... it would be like trying to convert your age into gallons.
You could use a standard kitchen scale to measure out 10.5g of rock salt accurately. If you don't have a scale, you can estimate using measuring spoons, keeping in mind that 1 teaspoon of rock salt is approximately 6g.
A ruler or a measuring tape could be used to measure the dimensions (length, width, height) of a rock, while a scale can determine its weight. For irregularly shaped rocks, a water displacement method can be used to calculate volume, which can then be used to estimate density or mass.
