Diagonal

Diagonal is calculated by the use of Pythagorean theorem:
Diagonal =  w² + h²
where w = sensor width and h = sensor height

Fujifilm X-A7 diagonal

w = 23.50 mm
h = 15.70 mm
Diagonal =  23.50² + 15.70²   = 28.26 mm

Canon M6 Mark II diagonal

w = 22.30 mm
h = 14.90 mm
Diagonal =  22.30² + 14.90²   = 26.82 mm


Surface area

Surface area is calculated by multiplying the width and the height of a sensor.

X-A7 sensor area

Width = 23.50 mm
Height = 15.70 mm

Surface area = 23.50 × 15.70 = 368.95 mm²

M6 Mark II sensor area

Width = 22.30 mm
Height = 14.90 mm

Surface area = 22.30 × 14.90 = 332.27 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

X-A7 pixel pitch

Sensor width = 23.50 mm
Sensor resolution width = 6026 pixels
Pixel pitch =   23.50  × 1000  = 3.9 µm
6026

M6 Mark II pixel pitch

Sensor width = 22.30 mm
Sensor resolution width = 6983 pixels
Pixel pitch =   22.30  × 1000  = 3.19 µm
6983


Pixel area

The area of one pixel can be calculated by simply squaring the pixel pitch:
Pixel area = pixel pitch²

You could also divide sensor surface area with effective megapixels:
Pixel area =   sensor surface area in mm²
effective megapixels

X-A7 pixel area

Pixel pitch = 3.9 µm

Pixel area = 3.9² = 15.21 µm²

M6 Mark II pixel area

Pixel pitch = 3.19 µm

Pixel area = 3.19² = 10.18 µm²


Pixel density

Pixel density can be calculated with the following 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

X-A7 pixel density

Sensor resolution width = 6026 pixels
Sensor width = 2.35 cm

Pixel density = (6026 / 2.35)² / 1000000 = 6.58 MP/cm²

M6 Mark II pixel density

Sensor resolution width = 6983 pixels
Sensor width = 2.23 cm

Pixel density = (6983 / 2.23)² / 1000000 = 9.81 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:
(X × r) × X = effective megapixels × 1000000    →   
X =  effective megapixels × 1000000
r
3. To get sensor resolution we then multiply X with the corresponding ratio:

Resolution horizontal: X × r
Resolution vertical: X

X-A7 sensor resolution

Sensor width = 23.50 mm
Sensor height = 15.70 mm
Effective megapixels = 24.20
r = 23.50/15.70 = 1.5
X =  24.20 × 1000000  = 4017
1.5
Resolution horizontal: X × r = 4017 × 1.5 = 6026
Resolution vertical: X = 4017

Sensor resolution = 6026 x 4017

M6 Mark II sensor resolution

Sensor width = 22.30 mm
Sensor height = 14.90 mm
Effective megapixels = 32.50
r = 22.30/14.90 = 1.5
X =  32.50 × 1000000  = 4655
1.5
Resolution horizontal: X × r = 4655 × 1.5 = 6983
Resolution vertical: X = 4655

Sensor resolution = 6983 x 4655


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


X-A7 crop factor

Sensor diagonal in mm = 28.26 mm
Crop factor =   43.27  = 1.53
28.26

M6 Mark II crop factor

Sensor diagonal in mm = 26.82 mm
Crop factor =   43.27  = 1.61
26.82

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).

X-A7 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 X-A7, take the aperture of the lens you're using and multiply it with crop factor.

Crop factor for Fujifilm X-A7 is 1.53

M6 Mark II 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 Canon M6 Mark II, take the aperture of the lens you're using and multiply it with crop factor.

Crop factor for Canon M6 Mark II is 1.61
