A standard ruler is typically 30cm long, so an object that is 19.5cm long could be a smaller ruler, a pencil, or a regular sized envelope.
The weight of a foot ruler is probably about 1 pound a little under a pound, but it is extremely light.
The weight of a ruler in newtons would depend on its mass and the acceleration due to gravity. Typically, a standard ruler would have a very small mass, so its weight in newtons would be very minimal, likely less than 1 newton.
A ruler floats in water because its density is lower than that of water. This means that the weight of the water it displaces is greater than its own weight, allowing it to float.

A normal ruler from England measures 30cm and 12inches, or 15cm and 5 inches depending on how big you want it.
On a ruler 12" = about 30cm and 7" = about 18cm so 48cm approximately. 1'7" = 19" and inch to centimeter conversion is 2.54 then 19 x 2.54 = 48.26
