How do planes know how heavy they are?

Aircraft are not weighed prior to each flight, but the basic empty weight must be known and checked periodically per regulation. Aircraft are weighed simply using scales under the carriages :-) The other method is to use jacks. See further below for an image.

The most common reason is that there are no airstrips or airports on many of the small islands, so if a plane had to make an emergency landing, it would be difficult to find a place to land. Additionally, the Pacific Ocean is vast and remote, so if a plane were to go down, it would be very difficult to find.

That depends if you have several kg overweight and are asking for the price per kg or if you really just only have one single kg extra. For a singe kg above the limit you most probably will not get charged, especially not on a full service airline. There is usually a tolerance in the range of 2–3kg, sometimes up to 5.
