Convert weight by reading across a grid

Units To lays out weight units one to a row and amounts one to a column, so any amount reads in every unit at once: kilograms, pounds, stone, grams, milligrams and ounces, and for fun, bananas, bowling balls and blue whales. Type an amount the way you would say it, lay out a range of amounts, and see which figures are exact.

• Type an amount the way you would say it: 6 ft, 5' 10", 70 kg or 98.6F.
• Lay out a range of amounts: every 10, powers of ten, or a list pasted from a spreadsheet.
• See at a glance which figures are exact and which are rounded.
• Star the units you use most, and share or copy the grid.
