If you want to convert blood sugar levels between different measurement units, such as milligrams per deciliter (mg/dL) and millimoles per liter (mmol/L), you can use our Blood Sugar Converter.
Blood Sugar Conversion formulas
To convert from mg/dL to mmol/L:
mmol/L = mg/dL 18.01559
To convert from mmol/L to mg/dL:
mg/dL = mmol/L × 18.01559
These conversion factors are approximate, and actual conversion factors can vary slightly. However, the one provided is commonly used for blood glucose conversions.
For example, if you have a blood sugar level of 90 mg/dL and want to convert it to mmol/L:
mmol/L = 90 / 18.01559 ≈ 5.0 mmol/L
And if you have a blood sugar level of 7.5 mmol/L and want to convert it to mg/dL:
mg/dL = 7.5 × 18.01559 ≈ 135 mg/dL
Remember to consult with a healthcare professional for accurate interpretation and advice regarding blood sugar levels.
On our website you can calculate the blood volume and blood type.
Normal blood sugar levels
Normal blood sugar levels can vary depending on when the measurement is taken (fasting or after meals) and the units used for measurement (mg/dL or mmol/L). Here are general guidelines for normal blood sugar levels:
Fasting Blood Sugar:
- Normal in mg/dL: 70-99 mg/dL
- Normal in mmol/L: 3.9-5.5 mmol/L
Postprandial (After Meals) Blood Sugar:
- Normal in mg/dL: Less than 140 mg/dL (measured 2 hours after eating)
- Normal in mmol/L: Less than 7.8 mmol/L (measured 2 hours after eating)
These values are general guidelines, and individual targets may vary. It's essential to note that specific health conditions, medications, and individual circumstances can affect blood sugar levels. If you have concerns about your blood sugar levels, it's best to consult with a healthcare professional for personalized advice and interpretation. Regular monitoring and consultation with a healthcare provider are crucial for managing blood sugar levels effectively.
Hypoglycemia (Low Blood Sugar):
Hypoglycemia, or low blood sugar, occurs when blood glucose levels fall below normal. The specific blood sugar level at which hypoglycemia is defined can vary, but it is generally considered to be below 70 mg/dL (3.9 mmol/L) in adults.
Typically, hypoglycemia is diagnosed when blood glucose levels are below 70 mg/dL (3.9 mmol/L).
However, it's important to note that individual responses to low blood sugar can vary, and some people may experience symptoms even when their blood sugar is slightly higher than this threshold. Symptoms are often more critical than the specific numeric value.
Hyperglycemia (High Blood Sugar):
Hyperglycemia refers to elevated levels of blood glucose (sugar). The specific blood sugar level at which hyperglycemia is diagnosed can vary, and it is often defined based on different circumstances such as fasting or postprandial (after meals).
Blood sugar levels indicative of hyperglycemia may include:
Fasting Blood Sugar:
Typically diagnosed when fasting blood glucose levels are consistently above 126 mg/dL (7.0 mmol/L) on two separate tests.
Postprandial (2 hours after a meal):
Blood sugar levels exceeding 200 mg/dL (11.1 mmol/L) may be considered indicative of hyperglycemia.
It's important to note that target blood sugar levels can vary based on individual health conditions, age, and other factors. For individuals with diabetes, target ranges are often established in consultation with healthcare providers.
