It's called the Scoville Scale. It measures the the capsaicin content of the pepper, and then ranks it. The more capsaicin, the hotter the pepper.
You see, capsaicin stimulates nerve endings in the skin that the brain interprets as heat. It sends out pain, heat, and dryness signals as a result - and essentially makes it feel like you're holding a hot coal in your mouth.
The hottest pepper in the world - at 1.5 million SHU (Scoville Heat Units) - is the Naga Jolokia pepper. It grows wild in Bangladesh. People who aren't accustomed to the heat of the pepper have reported passing out. Some people have even experienced a sort of anaphylactic shock due to the heat.

Hence, someone who eats spicy food regularly will grow a tolerance for even spicier foods as the nerves on the tongue have become 'numb' to capsaicin.
The appropriate unit is grams.
The unit of frequency is "Hertz", abbreviated "Hz". Also called "cycles". Also called "per second".
Spiciness is increased by adding more spices to the food. Spiciness cannot be decreased except by increasing the amount of the food without increasing the amount of spices.
Because of its spiciness, flavoring, and its delicacy.
The SI unit for energy - any type of energy - is the joule. For food, another unit, the calorie, is still often used.
