The first step when using the App is to decide on the scale you require by selecting either Scale Up or Scale Down, the button will show the setting and also the ratio box will swap from 1:*** to ***:1. Then decide which unit of measure you are converting, either Metric or Imperial, again the units will update to show m, cm, mm or ft, in, 16ths.
Once scaling and unit are set, adjust the slider to set a scale in the ratio box, you can also use the fine-tune buttons to set the ratio if on a small device.
Once selected you can then enter your original size in the text fields in the top purple area, with a size entered and the slider moved, the size in the bottom purple text fields will automatically update, allowing you to calculate the scale which best suits your needs.
