Carb content of meal serving: With the Nutritional Information of the product, enter the serving size in grams, ounces or units (spoons, pieces, slices, cups, etc.). Enter the grams of carbs that the label says, and then enter the food quantity. Hit the "Carb content is" button, and you'll get the grams of carbs of your food quantity.

Bolus insulin calculation amd BG increase for an amount of carbs: With your ICR (Insulin to Carb Ratio, that is how many grams of carb are compensated with a single insulin unit) and the grams of carbs you've consumed (the value is updated automatically when you calculate the Carb content of meal serving, but you can change it if you want to), hit the "Convert to" button and it'll tell you how many Units of bolus insulin you need. This DOES NOT take in account if the carbs are absorved slower or faster, it's just the plain calculation.

In the next line, you enter your BG to Insulin Ratio (that is how many mg/dl or mmol/ltr a unit of insulin will reduce from your BG), and it'll calculate how much your BG would increase with no bolus compensation.

Insulin units to reach target BG: With your current BG and the desired target, together your BG to Insulin Ratio, with the "Insulin compensation is" button it'll calculate how many units you need to reach that target.

BG conversion to A1c and to other units: If you want -say, with the average function of your BG Meter- see what you A1c would correspond to a certain BG value, hit the "Convert to" button. At the same time, if you're in a place where the other untis for BG are used (either mg/dl or mmol/ltr), it'll give you the equivalent conversion.

BMI for Weight and Height: With your Weight and Height and whatever units you use, the "Convert to" button will give you your Body Mass Index.

All these are just plain calculations that apply straight linear formulas for Insulin, compensation. They do no t replace medical advise. Whilst care has been taken to make them accurate, use at your own risk and responsibility.

Tips: Up

Most of the BG meters measure BG in mg/dl. However, in a few countries (like Canada), it is measured in mmol/ltr. Ensure you're using the right units for each one of the boxes.
