The blood sugar or blood glucose level is the amount of glucose (sugar) present in the blood of a human. Use this blood glucose calculator to estimate the level of sugar content present in a patient. The normal blood glucose (sugar) level in humans is about 5.5 mmol/L (100 mg/dL); however, this level fluctuates throughout the day.

Normal for person without diabetes: 70–99 mg/dl (3.9–5.5 mmol/L)
Official ADA recommendation for someone with diabetes: 80–130 mg/dl (4.5–7.2 mmol/L)
