Worked examples
Converting 5 torr
Multiply 5 by 0.13332237. That gives 0.666612 kilopascals. A quick sanity check: one torr is smaller than one kilopascal, so the number should get smaller — and it does.
Converting 72 torr
72 × 0.13332237 = 9.5992 kilopascals. Working backwards, 9.5992 ÷ 0.13332237 returns 72 torr, which confirms the factor is applied the right way round.
How to read your score
Frequently asked questions
How many kilopascals are in one torr?
Exactly 0.1333223684. Every conversion on this page is that single number multiplied by your input, so the result carries no rounding error beyond what is shown.
What is the formula to convert torr to kilopascals?
Kilopascals = torr × 0.1333223684. To reverse it, divide instead: torr = kilopascals ÷ 0.1333223684, which is the same as multiplying by 7.500616827.
Is the torr bigger than the kilopascal?
No. One torr is only 0.133322 of a kilopascal, so the kilopascal is the larger unit.
Why does my answer differ slightly from other torr to kilopascals converters?
Most differences come from rounding the factor too early. This tool keeps full double precision through the calculation and only rounds at the final display step, and it also shows the unrounded value so you can see exactly where any difference appears.
