Convert Pascal to Megapascal
1 pascal = 0.000001 megapascal (MPa). For example, 10 pascal = 0.00001 megapascal and 100 pascal = 0.0001 megapascal. Type any value below to convert pascal to megapascal both ways — it runs entirely in your browser.
Quick answer: Pascal to Megapascal
1 Pascal = 0.000001 Megapascal (Pa → MPa). To convert pascal to megapascal, multiply by 0.000001. To convert megapascal to pascal, multiply by 1,000,000. 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 pascal-to-megapascal questions.
How to convert Pascal to Megapascal
To convert pascal to megapascal, multiply the number of pascal by the conversion factor 0.000001, because 1 Pa = 0.000001 MPa. The conversion is linear, so the same factor works for any value — whole numbers, decimals or fractions. For the reverse direction, 1 MPa = 1,000,000 Pa, so you divide by 0.000001 (or multiply by 1,000,000) to turn megapascal back into pascal.
MPa = Pa × 0.000001 ·
Pa = MPa × 1,000,000
- Write down the value you want to convert, in pascal.
- Multiply it by 0.000001.
- The result is the same area/length/quantity expressed in megapascal.

Each row shows the exact arithmetic so you can follow the conversion step by step. For example, 5 pascal is 0.000005 megapascal because 5 Pa × 0.000001 = 0.000005 MPa.

Pascal vs Megapascal: which is bigger?
A megapascal is the larger unit: one megapascal equals 1,000,000 pascals. Put another way, you need 1,000,000 pascals to make a single megapascal.
What is a Pascal? History, origin and usage
The pascal is named after Blaise Pascal, who in 1648 had his brother-in-law carry a mercury barometer up the Puy de Dôme in central France and watch the mercury column fall as he climbed. That experiment showed air has weight and that the pressure it exerts drops with height. The unit itself is much younger: the name was adopted by the General Conference on Weights and Measures in 1971, replacing the older habit of writing pressures as "newtons per square metre".
The pascal is the SI unit of pressure and the base every other unit on this page is defined against. On its own it is awkwardly small for daily life — a sheet of paper resting on a table presses down with only a few pascals — so real-world figures are almost always given with a prefix: hectopascals for weather, kilopascals for tyres and gas, megapascals for concrete and hydraulics.
One pascal is one newton spread over one square metre, which is about the pressure of a five-rupee coin lying flat on a table. Because pressure is force divided by area, the same push concentrated into a smaller area gives a much higher pressure — which is why a drawing pin goes into a wall and your thumb does not.
What is a Megapascal? History, origin and usage
The megapascal became the standard way to state material strength as structural engineering codes moved to SI. It replaced a patchwork of older units — kilograms-force per square centimetre in Europe and Asia, pounds per square inch in the United States and Britain — that made international standards hard to compare.
Megapascals are used wherever pressures or stresses are large: concrete and steel strength, hydraulic systems, injection moulding, and the pressure ratings of pipes and pressure vessels. Ordinary structural concrete is commonly specified somewhere around 20 to 40 MPa.
One megapascal is a million pascals, and also exactly 10 bar, which makes the two easy to swap in your head. One megapascal is also the same as one newton per square millimetre — a coincidence engineers use constantly, because it lets a stress in MPa be read straight off a force in newtons and an area in square millimetres.

Tips for converting Pascal to Megapascal
- To go from pascal to megapascal, multiply by 0.000001; to go back, divide by 0.000001 (or multiply by 1,000,000).
- For a quick mental estimate, remember that 1 pascal ≈ 0.000001 megapascal, so 10 pascal ≈ 0.00001 megapascal.
- 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 Pascal to Megapascal converter
Type a number into the Pascal field and the equivalent in Megapascal 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 Megapascal field to convert the other way (megapascal to pascal). 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 Pa = 0.000001 MPa), 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 pascal-to-megapascal 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.
