Crop factor is 1.5 so for area and MP the factor is 1.5 x 1.5 = 2.25.

61 MP will crop to approx 27 MP.

1.5 is approximate not exact. The actual factor is 2.32

Fullframe Sensor area is 35.7 x 23.8 mm = 849.66 sq mm

APS-C Sensor area is 23.5 x 15.6 mm = 366.6 sq mm

849.66 ÷ 366.6 = 2.318

Thanks Brian, much appreciated.

John.
