How to Convert Teragray to Dekagray

Converting Teragray (TGy) to Dekagray (daGy) is a core calculation in Absorbed Radiation Dose, which quantifies the energy deposited in biological tissue or matter by ionizing radiation per unit mass. Both units reside within the International System of Units (SI) and share an identical physical dimension vector ([L² T⁻²]), separated strictly by a decimal order-of-magnitude factor (10^11). Because this shift involves integer powers of 10, the conversion is mathematically exact and free from decimal rounding or irrational fractional loss. Exactly 1 Teragray equals 1 × 10¹¹ Dekagray.

Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (gray (Gy)) without arbitrary rounding:

Vtarget=Vsource×(ksource→SIktarget→SI)V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)
Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)
1. Source SI Bridge (ksource):1 TGy = 1 × 10¹² gray (Gy)
2. Target SI Bridge (ktarget):1 daGy = 10 gray (Gy)
Step-by-step substitution for Teragray → Dekagray:V(daGy) = V(TGy) × ( 1 × 10¹² / 10 ) = V(TGy) × 1 × 10¹¹
Mathematical FormulaValue in Dekagray = Value in Teragray × 1 × 10¹¹Direct computational formula applied for standard conversion.
Worked Example

To convert 120 Teragray (TGy) to Dekagray (daGy): multiply 120 by 1 × 10¹¹ to get 1.2 × 10¹³ daGy. At an industrial engineering scale, 480 TGy converts to 4.8 × 10¹³ daGy.

Inverse check: 1 daGy = 1 × 10⁻¹¹ TGy.
