Diagonal
Diagonal is calculated by the use of Pythagorean theorem:
where w = sensor width and h = sensor height
Diagonal = √  w² + h² 
Fujifilm XPro3 diagonal
w = 23.50 mm
h = 15.60 mm
h = 15.60 mm
Diagonal = √  23.50² + 15.60²  = 28.21 mm 
Fujifilm XT1 diagonal
w = 23.60 mm
h = 15.60 mm
h = 15.60 mm
Diagonal = √  23.60² + 15.60²  = 28.29 mm 
Surface area
Surface area is calculated by multiplying the width and the height of a sensor.
XPro3 sensor area
Width = 23.50 mm
Height = 15.60 mm
Surface area = 23.50 × 15.60 = 366.60 mm²
Height = 15.60 mm
Surface area = 23.50 × 15.60 = 366.60 mm²
XT1 sensor area
Width = 23.60 mm
Height = 15.60 mm
Surface area = 23.60 × 15.60 = 368.16 mm²
Height = 15.60 mm
Surface area = 23.60 × 15.60 = 368.16 mm²
Pixel pitch
Pixel pitch is the distance from the center of one pixel to the center of the next measured in micrometers (µm). It can be calculated with the following formula:
Pixel pitch =  sensor width in mm  × 1000 
sensor resolution width in pixels 
XPro3 pixel pitch
Sensor width = 23.50 mm
Sensor resolution width = 6277 pixels
Sensor resolution width = 6277 pixels
Pixel pitch =  23.50  × 1000  = 3.74 µm 
6277 
XT1 pixel pitch
Sensor width = 23.60 mm
Sensor resolution width = 4962 pixels
Sensor resolution width = 4962 pixels
Pixel pitch =  23.60  × 1000  = 4.76 µm 
4962 
Pixel area
The area of one pixel can be calculated by simply squaring the pixel pitch:
You could also divide sensor surface area with effective megapixels:
Pixel area = pixel pitch²
You could also divide sensor surface area with effective megapixels:
Pixel area =  sensor surface area in mm² 
effective megapixels 
XPro3 pixel area
Pixel pitch = 3.74 µm
Pixel area = 3.74² = 13.99 µm²
Pixel area = 3.74² = 13.99 µm²
XT1 pixel area
Pixel pitch = 4.76 µm
Pixel area = 4.76² = 22.66 µm²
Pixel area = 4.76² = 22.66 µm²
Pixel density
Pixel density can be calculated with the following formula:
One could also use this formula:
Pixel density = (  sensor resolution width in pixels  )² / 1000000 
sensor width in cm 
One could also use this formula:
Pixel density =  effective megapixels × 1000000  / 10000 
sensor surface area in mm² 
XPro3 pixel density
Sensor resolution width = 6277 pixels
Sensor width = 2.35 cm
Pixel density = (6277 / 2.35)² / 1000000 = 7.13 MP/cm²
Sensor width = 2.35 cm
Pixel density = (6277 / 2.35)² / 1000000 = 7.13 MP/cm²
XT1 pixel density
Sensor resolution width = 4962 pixels
Sensor width = 2.36 cm
Pixel density = (4962 / 2.36)² / 1000000 = 4.42 MP/cm²
Sensor width = 2.36 cm
Pixel density = (4962 / 2.36)² / 1000000 = 4.42 MP/cm²
Sensor resolution
Sensor resolution is calculated from sensor size and effective megapixels. It's slightly higher than maximum (not interpolated) image resolution which is usually stated on camera specifications. Sensor resolution is used in pixel pitch, pixel area, and pixel density formula. For sake of simplicity, we're going to calculate it in 3 stages.
1. First we need to find the ratio between horizontal and vertical length by dividing the former with the latter (aspect ratio). It's usually 1.33 (4:3) or 1.5 (3:2), but not always.
2. With the ratio (r) known we can calculate the X from the formula below, where X is a vertical number of pixels:
3. To get sensor resolution we then multiply X with the corresponding ratio:
Resolution horizontal: X × r
Resolution vertical: X
1. First we need to find the ratio between horizontal and vertical length by dividing the former with the latter (aspect ratio). It's usually 1.33 (4:3) or 1.5 (3:2), but not always.
2. With the ratio (r) known we can calculate the X from the formula below, where X is a vertical number of pixels:
(X × r) × X = effective megapixels × 1000000 → 

Resolution horizontal: X × r
Resolution vertical: X
XPro3 sensor resolution
Sensor width = 23.50 mm
Sensor height = 15.60 mm
Effective megapixels = 26.10
Resolution horizontal: X × r = 4157 × 1.51 = 6277
Resolution vertical: X = 4157
Sensor resolution = 6277 x 4157
Sensor height = 15.60 mm
Effective megapixels = 26.10
r = 23.50/15.60 = 1.51 

Resolution vertical: X = 4157
Sensor resolution = 6277 x 4157
XT1 sensor resolution
Sensor width = 23.60 mm
Sensor height = 15.60 mm
Effective megapixels = 16.30
Resolution horizontal: X × r = 3286 × 1.51 = 4962
Resolution vertical: X = 3286
Sensor resolution = 4962 x 3286
Sensor height = 15.60 mm
Effective megapixels = 16.30
r = 23.60/15.60 = 1.51 

Resolution vertical: X = 3286
Sensor resolution = 4962 x 3286
Crop factor
Crop factor or focal length multiplier is calculated by dividing the diagonal of 35 mm film (43.27 mm) with the diagonal of the sensor.
Crop factor =  43.27 mm 
sensor diagonal in mm 
XPro3 crop factor
Sensor diagonal in mm = 28.21 mm
Crop factor =  43.27  = 1.53 
28.21 
XT1 crop factor
Sensor diagonal in mm = 28.29 mm
Crop factor =  43.27  = 1.53

35 mm equivalent aperture
Equivalent aperture (in 135 film terms) is calculated by multiplying lens aperture with crop factor (a.k.a. focal length multiplier).
XPro3 equivalent aperture
Aperture is a lens characteristic, so it's calculated only for fixed lens cameras. If you want to know the equivalent aperture for Fujifilm XPro3, take the aperture of the lens you're using and multiply it with crop factor.
Crop factor for Fujifilm XPro3 is 1.53
Crop factor for Fujifilm XPro3 is 1.53
XT1 equivalent aperture
