JMMG Tools are a useful tool collection for your web browser.
Here you will find numerous functions for calculating dates.
Displays an analog clock.
A color mixer for RGB colors.
Here you can compare two lengths and determine their mean value.
Here you can convert values between different units, for example kilometers to miles or degrees Celsius to degrees Fahrenheit.
Here you can measure the route that you have covered. The function requires very precise position data. If the reception of the position data should be interrupted in the meantime, the function adds the straight line distance between the last measured point and the current point when position data will be received again.
Find out the IP address with which you are on the Internet.
Find your location here and show the distance to large cities. Measure the direct distance between two points by saving your current location as your starting point, then go to the second point. For example, save your home as a starting point and see how far you are from it when you are on the move.
Plays a high frequency sound.
Here you can visualize ratios (e.g. 1:10000).
You can measure time with the stopwatch. If required, the reference data contains data relating to the measured time, for example which distance is covered at a certain speed within the measured time.
Here you can edit text and, for example, convert it to upper or lower case. Insert or write an existing text using the clipboard. If necessary, you can switch off the spell check of your operating system. After editing the text, copy it back to the clipboard so that you can use it in another application.
