# Thyroid Conversion Calculator Online

The Thyroid Conversion Calculator is an essential online tool that simplifies the conversion between the two main forms of thyroid medication: T4 and T3. This calculator helps adjust dosages correctly, ensuring patients receive the appropriate level of thyroid hormones for their specific conditions. By providing a quick and accurate conversion, it aids in maintaining the optimal therapeutic balance.

## Formula of Thyroid Conversion Calculator

The Thyroid Conversion Calculator utilizes straightforward mathematical formulas to convert thyroid hormone dosages:

• T3 dose in mcg = T4 dose in mcg / 4 This formula helps patients or healthcare providers convert Levothyroxine (T4), the standard thyroid hormone replacement, to Liothyronine (T3), the more biologically active form.
• T4 dose in mcg = T3 dose in mcg * 4 This conversion is used when switching from Liothyronine to Levothyroxine, ensuring that patients transitioning between different forms maintain appropriate hormone levels.
• Total thyroid hormone dose = T4 dose in mcg + (T3 dose in mcg * 4) Combining doses of T4 and T3 can be critical for patients requiring a more tailored therapy approach, accommodating unique metabolic needs.

## Useful Conversion Table

To further assist users, here’s a handy table with commonly used doses converted between T4 and T3, allowing quick reference without the need for manual calculations:

## Example of Thyroid Conversion Calculator

Imagine a patient is prescribed 100 mcg of Levothyroxine and needs to switch to Liothyronine. Using our calculator:

• Convert 100 mcg of T4 to T3: 100 / 4 = 25 mcg of T3 This example demonstrates how the calculator can be used to make quick and accurate medication adjustments.
