It depends on what the liter contains.
kg is a measure of weight; liter is a measure of volume
A liter is a unit of volume not weight, therefore to determine how much a liter weighs it depends on what you're measuring. A liter of water has a different weight than a liter of sand and so on.
it helps the surfboard stay balanced so when you go over waves the surfboard won't wobble or tip over as much
The weight of a liter of propylene glycol is approximately 1.036 kilograms.

not much
The force that a human body can exert on a surfboard is its weight. Weight is the gravitational force acting on a body's mass, and is determined by multiplying the acceleration due to gravity (g), 9.81m/s2, times the person's mass in kilograms. The unit for weight is the Newton (N). For example, if a person has a mass of 75.5kg, his weight in Newtons will be 75.5kg x 9.81m/s2 = 741N.
5.0 liter motor engines weight at least 200 pounds
1.2 kgs
approx. 8.35 lb
assuming density is 1g/cm3, 1 liter should weigh 1 kilogram
