ppm - or parts per million - is commonly used as a unit of concentration.
- 1 ppm = 10-6 = 0.0001 % = 0.001 ‰
- 1 000 ppm = 0.1 %
- 10 000 ppm = 1%
What does ppm really stand for?
- 15 % turned into serious romantic couple.
- 25 % remained Friends with benefits.
- 28 % quit the benefits and remained just friends.
- 31 % were no longer in touch.
What is ppm and how do I calculate it?
ppm is used to measure chemical concentration, usually in a solution of water. Solute concentration of 1 ppm is solute concentration of 1/1000000 of the solution. The concentration C in ppm is calculated from the solute mass m solute in milligrams and the solution mass m solution in milligrams . C(ppm) = 1000000 × msolute / ( msolution + msolute)
What does ppm stand for in medical terms?
parts per million is abbreviated as ppm, definition: one ppm means one (defect or event) in a million or 1/1, is the premier clinical laboratory accreditation, including webpages,900 molecules of air, co poses a greater threat to victims and firefighters than does oxygen deprivation or heat, paba functions in the breakdown and utilization of …
What does ppm stand for in a computer?
ppm is part per millions. is an specification for devices that said the quality. Ex. the oscillator is +-50ppm means that if your frequency is 10 mhz you can have an error of +- 500 Hz.
What does PPM stand for in construction?
PPM stands for Planned Preventive Maintenance, which is also called planned maintenance or scheduled maintenance. PPM maintenance is carried out on an asset (like a piece of equipment, a property, or an element of a property) on a regular basis.
What does PPM mean in electrical?
Surge Protective DevicesSurge Protective Devices (SPD) are used to protect the electrical installation, which consists of the consumer unit, wiring and accessories, from electrical power surges known as transient overvoltages.

What does PPM stand for in healthcare?
Permanent Pacemaker (PPM)
What is surge in electrical?
In general a surge is a transient wave of current, voltage or power in an electric circuit. In power systems in particular – and this is likely the most common context that we relate surges to – a surge, or transient, is a subcycle overvoltage with a duration of less than a half-cycle of the normal voltage waveform.
What is an Rccb and what does it do?
A Residual Current Circuit Breaker (RCCB) is an important safety measure when it comes to protection of electrical circuits. It is a current sensing device, which can automatically measure and disconnect the circuit whenever a fault occurs in the connected circuit or the current exceeds the rated sensitivity.
Why is ppm a useful measurement?
Why is the PPM Measurement Important? In water treatment, we use ppm to measure the amounts of minerals and gasses dissolved in water. We use water as a medium to transfer heat. As the water transfers heat, these dissolved impurities in ppm can cause problems in the equipment such as mineral scale and corrosion.
What is ppm example?
For example, 1 ppm chlorine represents one part of chlorine in one million parts of air by weight, which is 1.45 mg/m3. The ppm unit is mainly used in North America.
What is ppm equal to?
Parts per million and parts per billion may be converted from one to the other using this relationship: 1 part per million = 1,000 parts per billion. For water, 1 ppm = approximately 1 mg/L (also written as mg/l) of contaminant in water, and 1 ppb = 1 ug/L (also written as ug/l).
What does ppm stand for in NHS?
ppm+ (Patient Pathway Manager) is LTHT's electronic health record, built on the latest web technology and benefitting from a programme of continuous development to deliver an agile, multi-functional EHR.
What is a PPM in nursing?
What is a professional practice model (PPM)? A professional practice model describes how registered nurses practice, collaborate, communicate, and develop professionally to provide the highest-quality care for those served by the organization.
What does PPM mean?
PPM stands for Parts Per Million. Those of us in the pool business often take acronyms for granted, as though everyone knows them. This article will explain PPM and why it matters.
What is PPM in water?
It tells us the density of a given substance dissolved in water. Examples include free chlorine, calcium hardness, and total alkalinity.
How many PPB is phosphate?
Another exception is phosphate, which is usually measured in Parts Per Billion (PPB). One PPB is one-thousandth of one PPM. So phosphate concentration is hopefully below 1 PPM, which would be 1,000 PPB. So to convert PPM to PPB, multiply by 1,000, and vice versa.
What is PPM in pool chemistry?
It tells us the amount–expressed as concentration (or density) in the water–of a given substance. Or, in the case of Total Alkalinity (TA), the sum of several substances.
What is the standard unit of measurement for swimming pool chemistry?
The standard unit of measurement in swimming pool chemistry is parts per million (PPM). PPM's metric equivalent is milligrams per liter (mg/L). One milligram is 1/1000th of a milliliter, and one milliliter is 1/1000th of a Liter. A thousand times a thousand equals one million, hence the term parts per million.
What is ppm in chemistry?
Parts per million (ppm) is how many parts a certain molecule or compound makes up within the one million parts of the whole solution. It's typically used to describe concentrations of chemicals dissolved in a solvent (typically water) or compounds in soil.
What Is Parts Per Million?
We're all (or should all be) familiar with talking about things as a percentage, such as 'this hamburger contains 50% of my daily recommended calories.' Percent really means parts per hundred, so, similar to percent, is parts per million, only we're usually talking about much smaller concentrations. If we were to refer to 2 parts per million, then this would be 0.0002%, and all of those zeros start to get confusing, so instead, we refer to parts per million for smaller concentrations.
How much salt is needed to make 50 ppm?
So for every 1000 mL of solution, we need to use 0.05 g of salt in order to make a 50 ppm salt-water solution. In order to make this solution we would put 50 ppm of salt into a 1 liter container, and then fill the container to the 1 liter line.
