From Part 1
FINDING THE ACTUAL DISTANCE
TOPIC CODE: SCL421ARTC


 

To find actual Distance we use two methods:

(1) If given scale is statement scale, take the map distance multiply by given ground distance in the scale provided:

Example: if the scale is 1cm to 4km, take

MAP DITANCE X 4Km

if the scale is 1cm to 0.5km, take

MAP DITANCE X 0.5Km

PART A: SCALE CONVERSION:

Before we begin conversion of scale you have to acquire the basic knowledge of scale.

Scale is the ratio between  map distance and the  ground distance.

Scales are of the three types as indicated below:

(i) Small Scale        e.g.: 1:1000000

(ii) Medium Scale e.g.: 1:50000

(iii) Large scale      e.g. 1:200

CELSIUS, FAHRENHEIT AND KELVIN

Celsius (°C),  Fahrenheit (°F) and Kelvin (K) are units of recording temperature.

The Fahrenheit was proposed by Daniel Gabriel Fahrenheit. The scale is often mispelled as "farhenheit", "farenheit", "farhenhiet", or "farenhiet".

The Celsius scale is still sometimes called the "centigrade" scale because it is divided into 100 divisions. It was devised by Andres Celsius.

The Kelvin scale is named after the Belfast-born, Glasgow University engineer and physicist William Lord Kelvin (1824–1907), Read more .....
