100 lumens=1257 candlepower from what I have found
460 lumens for a standard automotive, not uprated.
It is a lot brighter than 50 candlepower and slightly less bright than 402 candlepower.
This is roughly 500 lumens
Approximately 15 lumens per watt for halogen, so 300 lumens.
They are one in the same just a different way of measuring the output of light. Much in the same way one would say a football field is 100 yards long it is also 300 ft. A rough answer to your question is 100 llumens equals about 26,500 candlepower. The term candlepower came about of course way back when everyone used candles in stead of modern lightbulbs. Llumens come from putting light on an object from a distance and maesuring the light at that point and distance. Very similar is horsepower and torque where horsepower is NOT a measured number on a dyno it is computed from torque output then converted from work over time.

About 80 lumens per watt of electric power is normal for LEDs.
A good projector will have 2000 or more lumens, but an LED projector will have much less.
the MK127 parachute flare is NATO rated at 125,000 candlepower.
