Absorbed Dose converter

teragray to megagray

Convert teragray (TGy) to megagray (MGy). Use an editable absorbed dose converter, conversion formula, and reference table.

1,000,000

1 TGy = 1,000,000 MGy

Calculated in your browser

Conversion formula

MGy = TGy × 1,000,000

One teragray equals 1,000,000 megagray. Multiply your value in teragray by this factor to get megagray. For the reverse conversion, divide by the same factor.

Worked example

To convert 5 teragray:
5 × 1,000,000 = 5,000,000 MGy

About these measurements

Absorbed dose measures energy deposited per unit mass.

The base reference used here is the gray. One teragray is 1e+12 base units; one megagray is 1,000,000 base units.

Important distinctions

Physical unit conversion only. Biological effect requires additional information and professional assessment.

Precision

The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.

Common questions
