Sensor size comparison
Sensor size is generally a good indicator of the quality of the camera. Sensors can vary greatly in size. As a general rule, the bigger the sensor, the better the image quality.

Bigger sensors are more effective because they have more surface area to capture light. An important factor when comparing digital cameras is also camera generation. Generally, newer sensors will outperform the older.

5D sensor is approx. 10.47x bigger than 808 PureView sensor.
Note: You are comparing sensors of very different generations. There is a gap of 7 years between Canon 5D (2005) and Nokia 808 PureView (2012). Seven years is a lot of time in terms of technology, meaning newer sensors are overall much more efficient than the older ones.
Pixel pitch
8.2 µm
1.4 µm
Pixel pitch tells you the distance from the center of one pixel (photosite) to the center of the next. It tells you how close the pixels are to each other.

The bigger the pixel pitch, the further apart they are and the bigger each pixel is. Bigger pixels tend to have better signal to noise ratio and greater dynamic range.
Difference: 6.8 µm (486%)
Pixel pitch of 5D is approx. 486% higher than pixel pitch of 808 PureView.
Pixel area
67.24 µm²
1.96 µm²
Pixel or photosite area affects how much light per pixel can be gathered. The larger it is the more light can be collected by a single pixel.

Larger pixels have the potential to collect more photons, resulting in greater dynamic range, while smaller pixels provide higher resolutions (more detail) for a given sensor size.

Pixel area difference: 65.28 µm² (3331%)
A pixel on Canon 5D sensor is approx. 3331% bigger than a pixel on Nokia 808 PureView.
Pixel density
1.49 MP/cm²
51.01 MP/cm²
Pixel density tells you how many million pixels fit or would fit in one square cm of the sensor.

Higher pixel density means smaller pixels and lower pixel density means larger pixels.
Difference: 49.52 µm (3323%)
Nokia 808 PureView has approx. 3323% higher pixel density than Canon 5D.

Diagonal

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

Canon 5D diagonal

w = 35.80 mm
h = 23.80 mm
Diagonal =  35.80² + 23.80²   = 42.99 mm

Nokia 808 PureView diagonal

w = 10.82 mm
h = 7.52 mm
Diagonal =  10.82² + 7.52²   = 13.18 mm


Surface area

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

5D sensor area

Width = 35.80 mm
Height = 23.80 mm

Surface area = 35.80 × 23.80 = 852.04 mm²

808 PureView sensor area

Width = 10.82 mm
Height = 7.52 mm

Surface area = 10.82 × 7.52 = 81.37 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

5D pixel pitch

Sensor width = 35.80 mm
Sensor resolution width = 4365 pixels
Pixel pitch =   35.80  × 1000  = 8.2 µm
4365

808 PureView pixel pitch

Sensor width = 10.82 mm
Sensor resolution width = 7728 pixels
Pixel pitch =   10.82  × 1000  = 1.4 µm
7728


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

5D pixel area

Pixel pitch = 8.2 µm

Pixel area = 8.2² = 67.24 µm²

808 PureView pixel area

Pixel pitch = 1.4 µm

Pixel area = 1.4² = 1.96 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

5D pixel density

Sensor resolution width = 4365 pixels
Sensor width = 3.58 cm

Pixel density = (4365 / 3.58)² / 1000000 = 1.49 MP/cm²

808 PureView pixel density

Sensor resolution width = 7728 pixels
Sensor width = 1.082 cm

Pixel density = (7728 / 1.082)² / 1000000 = 51.01 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

5D sensor resolution

Sensor width = 35.80 mm
Sensor height = 23.80 mm
Effective megapixels = 12.70
r = 35.80/23.80 = 1.5
X =  12.70 × 1000000  = 2910
1.5
Resolution horizontal: X × r = 2910 × 1.5 = 4365
Resolution vertical: X = 2910

Sensor resolution = 4365 x 2910

808 PureView sensor resolution

Sensor width = 10.82 mm
Sensor height = 7.52 mm
Effective megapixels = 41.48
r = 10.82/7.52 = 1.44
X =  41.48 × 1000000  = 5367
1.44
Resolution horizontal: X × r = 5367 × 1.44 = 7728
Resolution vertical: X = 5367

Sensor resolution = 7728 x 5367


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


5D crop factor

Sensor diagonal in mm = 42.99 mm
Crop factor =   43.27  = 1.01
42.99

808 PureView crop factor

Sensor diagonal in mm = 13.18 mm
Crop factor =   43.27  = 3.28
13.18

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).

5D 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 5D, take the aperture of the lens you're using and multiply it with crop factor.

Crop factor for Canon 5D is 1.01

808 PureView equivalent aperture

Crop factor = 3.28
Aperture = f2.4

35-mm equivalent aperture = (f2.4) × 3.28 = f7.9
