How to calculate price per gram
Start with a known package price and its weight. Divide the price by the number of grams:
Price per gram = package price ÷ package weight in grams
For example, if 500 grams costs 120, the price per gram is 120 ÷ 500 = 0.24. A 300-gram quantity would cost 300 × 0.24 = 72.
When calculating weight from a budget
Divide the amount you want to spend by the price per gram. If the unit price is 0.24 and your budget is 60, the available weight is 60 ÷ 0.24 = 250 grams.

How to prepare images for a clean PDF
A readable PDF begins before conversion. Place documents on a flat surface, use even light and keep the camera parallel to the page. Avoid shadows across text and check that every edge is visible.
Before creating the PDF
- Remove blurred or duplicate images.
- Rotate pages into the correct reading direction.
- Arrange pages in the final reading order.
- Check that small text remains readable.
For multi-file work, give the final PDF a recognizable name and confirm the page order before sharing. Radiant Image To PDF supports scanning, image conversion, merging and sharing.
