Exposure, absorbed dose, equivalent dose, and effective dose are distinct quantities; do not equate R and Sv without explicit context and assumptions.

Absorbed dose (manual basis)

If the entered value is interpreted as rad, then Gy = value × 0.01 → 0.0100000 Gy.

If the entered value is interpreted as Gy, then rad = value / 0.01 → 100.000 rad.

Exposure (R), absorbed dose (Gy/rad), equivalent dose (Sv/rem), and effective dose (Sv) are distinct. This page only applies numeric factors you select; it does not infer radiation type or quality factors.
