Key Calculators

Covering key concepts

Designed for fast user-first calculation of key questions relating to permille.

Permille Calculator

Calculate any value in permille (‰), then see the result as percent, decimal, ratio, and a 1,000-square visual.

Formula: permille = (part / whole) * 1000

Permille Change Calculator

Apply a permille rate to any starting value and see increase/decrease amount, new value, and an interactive before/after bar visual.

Formula: new value = base × (1 ± permille / 1000)

Permille To Percent Converter

Convert permille to percent with a worked formula, each calculation step, and a final plain-language answer statement.

Formula: percent = permille / 10

Percent To Permille Converter

Convert percent to permille with a worked formula, each calculation step, and a final plain-language answer statement.

Formula: permille = percent × 10

PPM, PPB, And Permille Converter

Convert between parts per billion (ppb), parts per million (ppm), permille, percent, and decimal values.

Formula: 1‰ = 1000 ppm = 1,000,000 ppb

Slope Permille Calculator

Convert slope between permille, percent, ratio, and degrees. Useful for roads, rail, drainage, and trails.

Formula: permille slope = (rise / run) * 1000

Rise From Slope And Run Calculator

Calculate rise from a slope given in permille or percent and a run given in metric or imperial distance units.

Formula: rise = run × slope

Price Per Thousand Calculator

Convert any total price and unit count into a per-thousand price for fair comparisons.

Formula: price per thousand = (price / units) * 1000

Permille Increase Calculator

Increase a value by a chosen permille rate and see the added amount, final value, and interactive before/after visual.

Formula: new value = base × (1 + permille / 1000)

Permille Decrease Calculator

Decrease a value by a chosen permille rate and see the reduction amount, final value, and interactive before/after visual.

Formula: new value = base × (1 - permille / 1000)

Percent Change Calculator

Apply a percent rate as either increase or decrease and get change amount, final value, and an interactive before/after visual.

Formula: new value = base × (1 ± percent / 100)

Percent Increase Calculator

Increase a value by a chosen percent and get both the increase amount and final value with an interactive visual.

Formula: new value = base × (1 + percent / 100)

Percent Decrease Calculator

Decrease a value by a chosen percent and get reduction amount, final value, and interactive before/after visual.

Formula: new value = base × (1 - percent / 100)

Incline Percent To Degrees Calculator

Convert incline percent to degrees and permille with a live slope-angle diagram and normalized rise/run view.

Formula: degrees = arctan(percent / 100) × (180/π)

Treadmill Incline Percent To Degrees Calculator

Convert treadmill incline percent to degrees and permille with a live slope diagram, then use a training reference table to pick appropriate incline zones.

Formula: degrees = arctan(percent / 100) × (180/π)

Scientific Notation To Permille Converter

Convert scientific notation like 3.5e-2 or 3.5 × 10^-2 into permille, with decimal expansion, percent cross-check, and worked steps.

Formula: permille = decimal × 1000
