Calculating Electric Field Strength of Three Point Charges - Convert to V/m

[RoundyDuffy]

Hey i worked out this answer for the electric field strength at a point due to three point charges.

E = -46736i + 46736j -39546k

How do i convert this to V/m?
eg. 12345 V/m

I have checked everywhere

Thanks for any help
