How do I estimate insulin bolus for carbs and correction?

Use the insulin bolus calculator with your insulin-to-carb ratio, correction factor, target glucose, and insulin on board. The output is educational and should be verified with your clinician plan or pump wizard.

What is the 500 and 1800 rule for diabetes dosing?

The 500 rule estimates grams of carbohydrate covered by 1 unit of insulin, and the 1800 rule estimates how many mg/dL 1 unit may lower glucose for rapid-acting insulin. They are starting estimates, not prescriptions.

How is A1C converted to average glucose?

The ADAG relation is eAG mg/dL = 28.7 x A1C - 46.7, with the reverse conversion A1C = (eAG + 46.7) / 28.7.

Every result stays beside its inputs, with the relevant boundary visible before you continue.

Tool 1

ICR + ISF estimator

Set baseline therapy values first, then run meal-dose tools with your own verified settings.

ResultYour estimated ratios will appear here.

Rule-of-500/1800 values are starting points, not fixed prescriptions.

Next: apply these values in the meal bolus calculator

Tool 2

Insulin bolus calculator

Combine carb coverage and correction context using settings you have already verified.

Calculated estimateComplete the inputs to see the calculation breakdown.

Educational estimate only. Verify with your clinician or regulated bolus calculator before dosing.

Next: add context for a high-fat meal

Tool 3

FPU extended bolus planner

Explore extended context for meals where fat and protein may delay the glucose response.

Planning viewFPU context and extension timing will appear here.

Warsaw-style FPU planning differs by person. Start conservatively and tune only with your care team.

Next: review the CGM outcome

Tool 4

TIR + GMI calculator

Translate a complete CGM summary into review metrics before discussing any setting change.

CGM reviewTIR, daily time, and GMI will appear here.

Consensus targets often reference at least 70% TIR for many adults. Individual goals vary.

Next: translate A1C and eAG

Tool 5

A1C and eAG converter

Bridge daily glucose logs and clinic lab language in either direction.

Converted valueYour A1C or eAG conversion will appear here.

Uses the ADAG relation: eAG (mg/dL) = 28.7 x A1C - 46.7. Educational conversion only — eAG is an estimate and can differ from your CGM mean glucose. Confirm interpretation with your care team.
