CIMA
Body Mass Index (BMI) and Other Indexes Calculator with Classification
CIMA is a program that provides an easy way to calculate a diversity of body indexes related to the fat content and energy needs, providing a way to control our weight: 1 - Body Mass Index (BMI), including both the traditional and the new proposed formulas, and provides a classification of the results. The evaluation takes in account the age groups (adults, children and the elderly). 2 - Body Adiposity Index (BAI). 3 - Basal Metabolic Rate (BMR) for Men and for Women. 4 - Body Fat Percentage (BFP). 5 - Total Daily Calories Needs based on the activity levels of the user lifestyle. The program supports 3 languages (English, European Portuguese and Brazilian Portuguese). IMPORTANT: CIMA works only with the International System of Units (SI). No other systems are allowed since SI is the standard one. CIMA may still require a depuration before becoming a mature program, but it is already functional and may be downloaded by anyone. -
