Enter the distance you were tested at and the distance a normal eye could read the same line from, and it returns your vision ratio. A larger second number means weaker distance vision. 4Ts Score Calculator (HIT) The 4Ts score estimates how likely a drop in platelets is caused by heparin-induced thrombocytopenia (HIT). It scores four features — the degree of Thrombocytopenia, the Timing of the platelet fall, the presence of Thrombosis, and whether oTher causes are present — from 0 to 2 each, for a total of 0 to 8. The total places a patient in a low, intermediate or high pre-test probability of HIT. 5/3/1 Program Calculator 5/3/1 Program Calculator is a health and wellness calculator that helps you calculate 5/3/1 program values from your input data.

This calculator compares the distance you walked, in metres, against an age-based predicted distance and reports it as a percentage of predicted. A lower percentage suggests reduced exercise capacity. 90 Minute Sleep Cycle Calculator Sleep runs in cycles of roughly 90 minutes, and waking at the end of a cycle leaves you feeling more refreshed than waking mid-cycle. This calculator takes your target sleep time and cycle length and tells you how many complete cycles fit and the actual sleep duration that lines up with a full cycle. Use it to plan a bedtime or wake-up that avoids interrupting deep sleep. A Body Shape Index Calculator A Body Shape Index (ABSI) combines your waist circumference with your BMI and height to judge how much of your weight sits around the middle. Enter your waist, height and weight and the calculator returns your ABSI, your BMI, and a rough risk band. A higher ABSI means more central fat for your size, which is linked to greater health risk independent of BMI.

Abdominal Volume Index Calculator The Abdominal Volume Index (AVI) estimates the volume of your abdomen from your waist and hip circumferences, giving a measure of central (belly) fat linked to metabolic risk. Enter your waist and hip in centimetres and the calculator returns your AVI and a rough interpretation. It is a screening estimate of abdominal obesity, not a diagnosis. ABSI Calculator The ABSI (A Body Shape Index) calculator scores how much your waist size stands out for your height and weight, then compares it to population norms by sex to give a z-score and risk band. Enter your sex, age, weight, height and waist circumference. Because it adjusts for BMI and height, ABSI captures central-fat risk that BMI alone misses.

ACFT Score Calculator (Simplified) This simplified ACFT calculator gives a rough fitness estimate from three Army Combat Fitness Test events: the 3-rep-max deadlift, the standing power throw and the sprint-drag-carry. Enter your results and it returns a combined score where stronger lifts and throws and faster carries push the number up. It is an unofficial training estimate, not the official six-event ACFT scoring. Acid-Base (ABG) Calculator This acid-base calculator classifies an arterial blood gas (ABG) as acidemia, alkalemia or normal based on blood pH. Enter the pH, along with pCO2 and bicarbonate (HCO3-) for context, and it flags whether the blood is too acidic, too alkaline or within the normal 7.35-7.45 range.

The two scales differ by a factor of 10: g/L = g/dL × 10, and g/dL = g/L ÷ 10. Albumin-to-Creatinine Ratio (ACR) Calculator The urine albumin-to-creatinine ratio (ACR) screens for early kidney damage by comparing albumin to creatinine in a urine sample. Enter your urine albumin and creatinine, and the calculator returns the ACR in mg/g with its category — normal, microalbuminuria or macroalbuminuria. A rising ACR is one of the earliest signs of kidney disease, especially in diabetes and high blood pressure. Albumin/Globulin (A/G) Ratio Calculator The Albumin/Globulin (A/G) Ratio Calculator works out the ratio of albumin to globulin in your blood from total protein and albumin. Globulin = total protein − albumin, and the A/G ratio = albumin ÷ globulin. A normal ratio is roughly 1.1 to 2.5.

Enter your measurements in centimetres to see your estimated body fat and whether it is within standard. Arterial Age Calculator Estimate your arterial (vascular) age from your blood pressure and chronological age. Higher systolic blood pressure suggests stiffer, older-acting arteries, so this simple screening estimate adjusts your real age upward as systolic pressure rises above 120 mmHg. Enter your blood pressure and age to see an indicative arterial age — it is an educational guide, not a diagnosis. Arterial Blood pH Calculator Convert a hydrogen-ion concentration [H⁺] into blood pH using pH = −log₁₀[H⁺]. Enter the [H⁺] in moles per litre (M) and the calculator returns the pH. For reference, normal arterial blood pH sits in a tight range of about 7.35–7.45.
