If it's a Calorie (capital C), it's a Kilocalorie (1000 calories). Food values are in Kilocalories (i.e. Calories). They just use Calories for simplicity.
One calorie is 4.18 joules and is the heat required to increase 1 gram of water (1 millilitre) to by 1 kelvin (same as degree C for you uneducated). A kilocalorie is 4.18 kilojoules. In many countries, the unit for energy on food labels is KJ rather than Calories.
If you're fat, you burn 1000 Calories jogging at 10kph for 1 hour. If you're thinner, less (maybe 800 or so). Burning that little bar will take you two minutes.
