Percentage calculator
Calculate percentages, percentage changes and discounted values. Check which value is the baseline. Percentage change divides the difference by the absolute baseline. Results show up to six decimal places.
Unit converter
Convert units of length, mass, temperature and data size. kB, MB and GB use powers of 1,000; KiB, MiB and GiB use powers of 1,024. Temperatures below absolute zero are rejected.
Average and statistics
Find the mean, median, sum, minimum and maximum of a list of numbers. Separate values with newlines, spaces or commas. Commas are separators, not thousands marks. Standard deviation is population standard deviation.
Split a bill
Divide a total by the number of people and see the remainder or overpayment. Uses whole monetary units. Shows the remaining amount for equal rounded-down payments and the excess if everyone rounds up.
Paper size and pixels
Find pixel dimensions for A-series, JIS B-series or Letter paper at a chosen DPI. B4 and B5 use JIS dimensions. Bleed is not included. This calculator does not edit image DPI metadata.
Sheet layout calculator
Compare how many cards or labels fit on a sheet in either orientation. Compares uniform grids in two orientations, not mixed-orientation optimal packing or printer margins. All dimensions are in millimeters.
