2026 ADA Standards of Care — Key Updates The ADA released its 2026 Standards of Care in December 2025. Notable changes include support for GLP-1 receptor agonist use in type 1 diabetes with obesity, expanded CGM and automated insulin delivery (AID) recommendations at diabetes onset, a new perioperative blood glucose target of 100–180 mg/dL (5.6–10.0 mmol/L), and tighter blood pressure goals for individuals with high cardiovascular or kidney risk. CGM is not yet approved for screening or diagnosis of diabetes.

Mmol/L to mg/dl Formula

The following formula is used to convert mmol/L to mg/dl. 

mg/dl = 18.018 * mmol/l

Formula source:  Critical-care study on sepsis (2008)

  • Where mg/dl is the milligrams per deciliter
  • mmol/l is the millimoles per liter

These units are also known as units of glucose concentration.

*Status indications are general guidelines only. Consult a doctor. Formula: mmol/L × 18.018 = mg/dl.

How do you convert mmol/L to mg/dL? In order to convert milligrams per deciliter, multiply the total amount of mmol/L by 18.018. This will convert the value into mg/dL.

How do you convert mg/dL to mmol/L? To convert the mg/dL into mmol/L, simply divide the total mg/dL by 18.018. The formula for this process is shown above.

Example Problem

how to calculate mg/dl from mmol/l?

First, determine the total number of millimoles per liter.

For this example, the total number of mmol/l is found to be 150.

Next, use the formula for the conversion above to determine the amount of mg/dl.

mg/dl = 18.018 * mmol/l

mg/dl = 18.018 * 150

mg/dl = 2700
