How to detail 200 amp service from 100 amp service? I am not an electrically minded person, but I hold the chance...

I am not an electrically minded person, but I hold the chance to cash my furnace and stove from Natural Gas to electric. That is if I have the correct services into my home. I live within an older mobile home so I am told I probably hold 80 or 100 amp service but I want to be sure. So that is my cross-question; Is there an stupid way to share what type of service I have?
Answers:    Look at the switch of your main circuit breaker. Check the one contained by the house and then progress check the outside disconnect also. If you have fuses, they will be 100 amps or smaller amount. Who is going to install the electric heat? He could make clear to you by looking also.
Check your breaker box for a "Main" breaker - will have the "AMP" number on it . . . OR check the service box outside for a Breaker or AMP rating.
I hold seen some elder mobile homes only wired for 60 amps.
