Calculate how many kcals are in one serving based on the reported grams of total carbs, fats and proteins...
total carbs=38g
fat=6g

In nutrition, a unit called the kilocalorie, also known as the diet calorie, is frequently mentioned.
This unit is equivalent to 1000 cal, and is the amount of heat energy required to raise or lower one kilogram (1 kg) of pure liquid water by 1º C or 1º K.
When the label on a package of food says that a serving contains 200 calories, it means that the sample would yield 200 kcal (not 200 cal) of heat energy if subjected to complete combustion.
Kilocalories are used (and misused) to express the amount of food consumed in a serving, a meal, or a day.

kcal stands for kilocalorie, which means 1000 calories. It's a bit confusing how they're named, since we use the word "calories" to refer to what we usually count in food, when in fact we're counting kilocalories.
A kcal is a measurement of energy, it's the amount required to raise the temperature of 1 kg of water by 1 degree C. A calorie is basically the same, but it's the amount of energy needed to raise the temperature of 1 gram of water by 1 degree.
If you see a food label, it's always in kcal, even if it says "calories." Otherwise your 170-calorie food would actually be .170 kcals, and you're on to a diet miracle. So no need to do any conversion!

kcals and calories are the same thing.
There are 4 calories per gram of protein and carbs
9 calories per gram of fat.
Therefor, 38x4=152
6x9=54
5x4=20
Total calories would be 226

there are 1000 calories in 1 kcal. to find how many calires is in something if it is given in kcals multiply the number by 1x10^3.

Light weights and high reps will give you high muscle endurance (think runners for examples) and get you cut and ripped and lean. High weights and low reps will give you that explosive strength. Think Arnold Swatzinagerizzer or whatever his last name is spelled. For you and the real world and hell for anyone in general, Endurance is much more practical. You will get strong and get the muscle endurance with both styles but more so with one over the other. High reps being 15-25 and low reps being 6-8 maybe up to 10. So if you cant do 20 for endurance, its to much weight. Vice sersa
