Quick answer: Kilopascal to Torr
1 Kilopascal = 7.500617 Torr (kPa → Torr). To convert kilopascal to torr, multiply by 7.500617. To convert torr to kilopascal, multiply by 0.1333224. The converter at the top does this instantly and both ways; the sections below give the formula, worked examples, a full conversion chart and answers to the most common kilopascal-to-torr questions.
How to convert Kilopascal to Torr
To convert kilopascal to torr, multiply the number of kilopascal by the conversion factor 7.500617, because 1 kPa = 7.500617 Torr. The conversion is linear, so the same factor works for any value — whole numbers, decimals or fractions. For the reverse direction, 1 Torr = 0.1333224 kPa, so you divide by 7.500617 (or multiply by 0.1333224) to turn torr back into kilopascal.
Torr = kPa × 7.500617 ·
kPa = Torr × 0.1333224
- Write down the value you want to convert, in kilopascal.
- Multiply it by 7.500617.
- The result is the same area/length/quantity expressed in torr.

Kilopascal vs Torr: which is bigger?
A kilopascal is the larger unit: one kilopascal equals 7.500617 torrs. Put another way, you need 7.500617 torrs to make a single kilopascal.
What is a Kilopascal? History, origin and usage
The kilopascal came into general use as countries converted their engineering standards to SI through the 1970s and 1980s. Canada, Australia and much of Europe moved tyre-pressure labels and gas-cylinder markings to kPa in that period, which is why a car built for one market often carries a door sticker in kPa and one built for another carries the same number in psi or bar.
Kilopascals are the workaday metric pressure unit: tyre pressures, medical gas supplies, water systems, ventilation and most mechanical engineering specifications. A car tyre is typically inflated to somewhere around 200 to 250 kPa.
One kilopascal is 1,000 pascals, and 100 kilopascals is very nearly one atmosphere — which is a useful mental shortcut, though the exact figure is 101.325 kPa, not 100.
What is a Torr? History, origin and usage
The torr honours Evangelista Torricelli, who built the first mercury barometer in 1643 and correctly explained that the column was held up by the weight of the air outside. The unit was named in the 1940s, and was defined as exactly one 760th of a standard atmosphere so that it would be tied to a fixed number rather than to the behaviour of real mercury.
Torr is the working unit of vacuum technology — vacuum pumps, freeze dryers, electron microscopes, semiconductor process chambers and mass spectrometers are all specified in torr or its subdivisions.
Because it is defined as a 760th of an atmosphere, 760 torr is one atmosphere exactly, by construction. It is very nearly the same as a millimetre of mercury but not exactly: the two differ by about one part in seven million, a gap that matters only in precision metrology and is the reason careful documents never treat the two names as interchangeable.

Tips for converting Kilopascal to Torr
- To go from kilopascal to torr, multiply by 7.500617; to go back, divide by 7.500617 (or multiply by 0.1333224).
- For a quick mental estimate, remember that 1 kilopascal ≈ 7.500617 torr, so 10 kilopascal ≈ 75.00617 torr.
- The converter above keeps full precision; the tables round for readability, so use the tool for exact figures.
- Both fields update live as you type — change either side to convert in that direction.
How to use this Kilopascal to Torr converter
Type a number into the Kilopascal field and the equivalent in Torr appears instantly — there is no “convert” button to press and nothing is sent to a server, so it works offline once the page has loaded and is safe for any data. You can also type into the Torr field to convert the other way (torr to kilopascal). Use the swap control to flip the two units, and copy the result with a single click. Because the calculation runs in your browser with full floating-point precision, the converter is more exact than the rounded figures shown in the reference chart above — use the chart for quick look-ups and the tool for precise work.
Accuracy and method
Every figure on this page — the formula, the worked examples, the conversion chart and the “convert to other units” tables — is computed from a single verified conversion factor (1 kPa = 7.500617 Torr), never copied from a hand-typed lookup table that could drift. That factor is derived from each unit’s definition in terms of a common base unit, and an automated check re-verifies all of the site’s factors on every update, so the numbers here stay correct over time. This matters for kilopascal-to-torr conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
Sources
- BIPM — The International System of Units (SI Brochure) — the defining document for the SI, published by the International Bureau of Weights and Measures. It fixes the base unit that this conversion resolves to, which is why the factor here can be exact rather than approximate.
- NIST — Definitions of the SI base units — the US National Institute of Standards and Technology reference for the SI base units, used here as an independent cross-check on the base-unit definition.
Pressure factors here come from fixed definitions, anchored to the pascal: a bar is exactly 100,000 Pa, one atmosphere is exactly 101,325 Pa, a torr is exactly a 760th of an atmosphere, and psi is built from the exact pound and the exact inch. Two of them — psi and the torr — work out to decimals that repeat forever, so where a number is shown rounded it is marked, not quietly trimmed.
Frequently asked questions
