Converting from Hectogray (hGy) to Milliroentgen (mR) | Radiation

What is Hectogray (hGy)

Hectogray (hGy) is a unit of ionizing radiation absorbed dose in the International System of Units (SI). It measures the amount of energy absorbed per unit mass of the irradiated material.

What is Milliroentgen (mR)

Milliroentgen (mR) is a traditional unit of exposure dose of X-rays or gamma rays. It measures the amount of ionization produced in the air by X-rays or gamma rays.

Conversion Formulas

The default conversion rate between Hectogray and Milliroentgen is:

• 1 (hGy) = 11500000 (mR)
• 1 (mR) = 0.00000008695652 (hGy)

Other conversion rates include:

• 6 (hGy) = 69000000 (mR)
• 6 (mR) = 0.0000005217391 (hGy)
• 10 (hGy) = 115000000 (mR)
• 10 (mR) = 0.0000008695652 (hGy)
• 2 (hGy) = 23000000 (mR)
• 2 (mR) = 0.000000173913 (hGy)

Examples

1. Converting 6 Hectogray (hGy) to Milliroentgen (mR):

6(hGy)×11500000=69000000(mR)

2. Converting 10 Milliroentgen (mR) to Hectogray (hGy):

10(mR)×0.00000008695652=0.0000008695652(hGy)

Use these formulas to perform conversions between Hectogray (hGy) and Milliroentgen (mR) to better understand radiation exposure levels.
