To convert 30 kilometers into miles we have to multiply 30 by the conversion factor in order to get the length amount from kilometers to miles. Let the speed of boat in still water be x km/hr & let the speed of stream be y km/hr For example, if you have speed in mph (miles per hour), time should also be in hours. Thus it's usage varies in different fields and departments. An example: on a map with the scale 1:20000, 3 centimeters accord to 0.6 kilometers in reality. This online calculator tool can be a great help for calculating time basing on such physical concepts as speed and distance. 30 km to mi conversion. About Speed Distance Time Calculator. Some people maybe interested in the conversion of this value as they may want to know the number miles in a '5K' run. The formula to be used here is 5 X 0.62, which gives 3.1 miles.

The Executive Director of the government's US Federal Highway Administration, Mr Jeffrey Paniati, had once written in a memo in 2008 that the Section 205 (c) (2) of National Highway System Designation Act passed in 1995 disallows the US from needing any State Department of Transport to officially use the metric system for any project development activity. Simply enter any desired location into the search function and you will get the shortest distance (air line) between the points, the route (route planner) as well as all important information. Also, French maps which were published in the year 1835 are seen to have scales that show myriametres and postal leagues or "lieues de Poste" equal to about 4,288 metres. Thus 1/3 T= 10 and T=30 minutes or ½ hour. 1 cm â 20000 cm 3 cm â 20000 * 3 cm = 60000 cm = 600 m = 0.6 km Convert km/h, meters per second and miles per hour.

The current usage varies in the United Kingdom, with road signs showing distances in miles, while at the same time, location-marker posts which are used for the purpose of reference by road construction engineers and also most emergency services personnel show the distance references in an unspecified unit which are kilometer based. So, 30 kilometers times 1000000 is equal to 3 × 10 7 millimeters. It accepts fractional values. In the year 1935, the widely respected, 'International Committee for Weights and Measures', abolished use of the prefix "myria" and along with it, the use of "myriametre". The distance is calculated in kilometers, miles and nautical miles, and the initial compass bearing/heading from the origin to the destination. Other tools to help with distance questions.
