Which unit is used in India?

Most Indian labs and glucometers report in mg/dL, while many European countries use mmol/L.

Does one high reading mean I have diabetes?

No. ADA guidelines require an abnormal result confirmed on a second, separate day (or a second test method like HbA1c) before diagnosing diabetes — a single reading, especially a random one, is a prompt to get properly tested, not a diagnosis.

What counts as "after eating" for this tool?

Clinically this means exactly 2 hours after the start of a meal (or a standardised 75g glucose drink in a lab OGTT test) — checking earlier or later than 2 hours can give a misleadingly high or low reading.

How we calculate

Resting energy (BMR): Mifflin-St Jeor equation (Mifflin et al., Am J Clin Nutr 1990): 10 × weight (kg) + 6.25 × height (cm) − 5 × age, then +5 for men or −161 for women. Daily calories: BMR × an activity factor (1.2 to 1.725). Weight loss uses a 500 kcal/day deficit (about 0.5 kg a week) and never goes below 1,500 kcal for men or 1,200 kcal for women; weight gain adds 300 kcal.

BMI: weight (kg) divided by height (m) squared, read against the Asian cut-offs from the WHO Expert Consultation (The Lancet, 2004) and the Indian consensus guidelines (Misra et al., 2009): healthy 18.5 to 22.9, overweight 23 to 24.9, obese 25 and above.
