Here's a calculator, but 1 candela = 1 lumen/steradian where steradians are calculated from the angle of the beam.

There's no direct conversion on candela and lumen.
Here are some of it:

1 footcandle = 1 lumen per square foot
1 footcandle = 10.76 lumen / sq-m
1 footcandle = 10.76 lux
1 lumen = 1/683 watts @ 555nm
1 Lux = 1 lumen / sq-m
1 watt second = 1 joule = 107 ergs
