A simple answer with a confusing reason. 171 kcal = 171 Calories 1 Calorie (upper case) = 1000 calories (lower case) = 1 kilocalorie (lower case) = amount of energy needed to raise 1 kg of water 1 degree celsius. On nutritional information, all the numbers are listed in Calories (i.e., kcal), while calories (lower case) are very rarely used in everyday language.
It all depends on the exercise that you do.
by doing cardiovascular exercise
As long as you are familiar with correct technique while doing the exercise, it's very possible to burn 20 calories a minute!!

Initially yes but overtime your body will be comfortable with the routined exercise and will burn less calories.
If you do it properly, it certainly will. Unlike cardio exercise that burns extra calories only during and immediately after exercise, if you do proper strength training you will increase your lean muscle mass, and doing that will cause you to burn more calories 24 hours a day.
How many calories you burn with exercise depends on how hard you exercise and how much you weigh. The more vigorous the exercise, the more calories per hour you can burn. Cross-country skiing, jogging and swimming are exercises that burn a significant number of calories per hour.
It depends on weight time your doing it and speed sometimes even heat!
