Straightline (as the crow flies) 234 miles / 377 km.
Driving: 468 km / 291 miles / almost 5 hours hours in the car.
Route map and directions.
I notice that Mapquest doesn't take you the coastal route. Undoubtedly the Mapquest route will be faster than taking the old Highway 101. But Highway 101 is much more scenic, includes places like Big Sur and Monterey on the way. You can stop and watch sea otters play in the surf or visit Hearst Castle. If you have time to go that way.
