I don't know about the ruler's body parts, they were probably not much different to those of his subjects. The use of the foot as a standard was pretty obvious, we can trace that back to the Romans and it probably went back far earlier. The yard as 3 feet is presumably based on a pace. I'm not sure why there are 12 inches in a foot, but the inch is I think based on the thumb. There are also 'hands' used in measuring horses, 1 hand is 4 inches-try it.
The metric system was invented by the French after their revolution. They divided the distance from the equator to the pole into 10,000 parts and called this the kilometer, the meter and centimeter followed.
So I don't see a connection between the two systems
They are used to measure different attributes of things.
They both use the same units for measuring time. Otherwise they are not similar.
FPS - Foot, Pound, Second is the English system CGS - Centimeter, Gram, Second is the metric system Second in both systems are equal
You don't have to.Time is measured in the same units in both the Metric and English systems.
both imperial and metric system is used but scientist use the metric system the most.the metric system is also called the international system also known as the SI unit.
Both. It is the inverse of the unit of time (second) which is used by both systems.
The only unit that appears in both the modern SI (metric) system and the old fashioned system is the second.
Well they are both used to measure things. Meters are the metric system and feet are the English system.

They are both metric units, otherwise, they are not alike.

Learn the metric system: it is used in all developed countries.
Both. It is the inverse of the unit of time (second) which is used by both systems.
Both systems have measurements for distance, area, volume, and mass or weight.
Both modern Metric and Money are decimal (10) based; rather than more older fractional (1/2, 1/12, 1/16ths) systems.
They are both metric units; otherwise, they have nothing in common.
For just about any type of unit, different units are used between the English system and the SI (metric) system. In both systems, there are units for length, area, volume, mass, force, temperature, etc.
The English system is based on arbitrary numbers and measurements, such as 12, 36, and 5,280. The Metric system - every aspect of it - is based on even multiples of ten, both going upward, and going downward. Just ten. Nothing else.
