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.

XE1 sensor is approx. 17.27x bigger than SL300R T sensor.
Note: You are comparing sensors of very different generations.
There is a gap of 9 years between Contax SL300R T (2003) and Fujifilm XE1 (2012).
Nine years is a lot of time in terms
of technology, meaning newer sensors are overall much more
efficient than the older ones.
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.
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.
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.

Diagonal
Diagonal is calculated by the use of Pythagorean theorem:
where w = sensor width and h = sensor height
Diagonal = √  w² + h² 
Contax SL300R T diagonal
The diagonal of SL300R T sensor is not 1/2.7 or 0.37" (9.4 mm) as you might expect, but approximately two thirds of
that value  6.66 mm. If you want to know why, see
sensor sizes.
w = 5.33 mm
h = 4.00 mm
w = 5.33 mm
h = 4.00 mm
Diagonal = √  5.33² + 4.00²  = 6.66 mm 
Fujifilm XE1 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.
SL300R T sensor area
Width = 5.33 mm
Height = 4.00 mm
Surface area = 5.33 × 4.00 = 21.32 mm²
Height = 4.00 mm
Surface area = 5.33 × 4.00 = 21.32 mm²
XE1 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 
SL300R T pixel pitch
Sensor width = 5.33 mm
Sensor resolution width = 2054 pixels
Sensor resolution width = 2054 pixels
Pixel pitch =  5.33  × 1000  = 2.59 µm 
2054 
XE1 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 
SL300R T pixel area
Pixel pitch = 2.59 µm
Pixel area = 2.59² = 6.71 µm²
Pixel area = 2.59² = 6.71 µm²
XE1 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 
SL300R T pixel density
Sensor resolution width = 2054 pixels
Sensor width = 0.533 cm
Pixel density = (2054 / 0.533)² / 1000000 = 14.85 MP/cm²
Sensor width = 0.533 cm
Pixel density = (2054 / 0.533)² / 1000000 = 14.85 MP/cm²
XE1 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

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
SL300R T sensor resolution
Sensor width = 5.33 mm
Sensor height = 4.00 mm
Effective megapixels = 3.17
Resolution horizontal: X × r = 1544 × 1.33 = 2054
Resolution vertical: X = 1544
Sensor resolution = 2054 x 1544
Sensor height = 4.00 mm
Effective megapixels = 3.17
r = 5.33/4.00 = 1.33 

Resolution vertical: X = 1544
Sensor resolution = 2054 x 1544
XE1 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 
SL300R T crop factor
Sensor diagonal in mm = 6.66 mm
Crop factor =  43.27  = 6.5

XE1 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).
SL300R T equivalent aperture
Crop factor = 6.5
Aperture = f2.8  f4.7
35mm equivalent aperture = (f2.8  f4.7) × 6.5 = f18.2  f30.6
Aperture = f2.8  f4.7
35mm equivalent aperture = (f2.8  f4.7) × 6.5 = f18.2  f30.6
XE1 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 XE1, take the aperture of the lens
you're using and multiply it with crop factor.
Crop factor for Fujifilm XE1 is 1.53
Crop factor for Fujifilm XE1 is 1.53
