Diagonal

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

Olympus OM-D E-M5 Mark III diagonal

w = 17.30 mm
h = 13.00 mm
Diagonal =  17.30² + 13.00²   = 21.64 mm

Canon M200 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.

OM-D E-M5 Mark III sensor area

Width = 17.30 mm
Height = 13.00 mm

Surface area = 17.30 × 13.00 = 224.90 mm²

M200 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

OM-D E-M5 Mark III pixel pitch

Sensor width = 17.30 mm
Sensor resolution width = 5208 pixels
Pixel pitch =   17.30  × 1000  = 3.32 µm
5208

M200 pixel pitch

Sensor width = 22.30 mm
Sensor resolution width = 6012 pixels
Pixel pitch =   22.30  × 1000  = 3.71 µm
6012


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

OM-D E-M5 Mark III pixel area

Pixel pitch = 3.32 µm

Pixel area = 3.32² = 11.02 µm²

M200 pixel area

Pixel pitch = 3.71 µm

Pixel area = 3.71² = 13.76 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

OM-D E-M5 Mark III pixel density

Sensor resolution width = 5208 pixels
Sensor width = 1.73 cm

Pixel density = (5208 / 1.73)² / 1000000 = 9.06 MP/cm²

M200 pixel density

Sensor resolution width = 6012 pixels
Sensor width = 2.23 cm

Pixel density = (6012 / 2.23)² / 1000000 = 7.27 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

OM-D E-M5 Mark III sensor resolution

Sensor width = 17.30 mm
Sensor height = 13.00 mm
Effective megapixels = 20.40
r = 17.30/13.00 = 1.33
X =  20.40 × 1000000  = 3916
1.33
Resolution horizontal: X × r = 3916 × 1.33 = 5208
Resolution vertical: X = 3916

Sensor resolution = 5208 x 3916

M200 sensor resolution

Sensor width = 22.30 mm
Sensor height = 14.90 mm
Effective megapixels = 24.10
r = 22.30/14.90 = 1.5
X =  24.10 × 1000000  = 4008
1.5
Resolution horizontal: X × r = 4008 × 1.5 = 6012
Resolution vertical: X = 4008

Sensor resolution = 6012 x 4008


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


OM-D E-M5 Mark III crop factor

Sensor diagonal in mm = 21.64 mm
Crop factor =   43.27  = 2
21.64

M200 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).

OM-D E-M5 Mark III 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 Olympus OM-D E-M5 Mark III, take the aperture of the lens you're using and multiply it with crop factor.

Crop factor for Olympus OM-D E-M5 Mark III is 2

M200 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 M200, take the aperture of the lens you're using and multiply it with crop factor.

Crop factor for Canon M200 is 1.61
