Viscosity Conversion

Features
Read full description

Viscosity Conversion - Easily convert between various types of units for Dynamic Viscosity, Kinematic Viscosity, and Dynamic Viscosity for Oil and Water. Viscosity is the state of being thick, sticky, and semi-fluid in consistency, primarily due to internal friction. It is quantified by a measure of the magnitude of internal friction, typically represented as the force per unit area resisting flow between parallel layers at a unit distance apart moving at unit speed relative to each other. Viscosity of a fluid indicates its resistance to gradual deformation under shear stress or tensile stress. In everyday terms, it's akin to the concept of "thickness." For instance, honey exhibits significantly higher viscosity compared to water. Fluid viscosity reflects its resistance to shear or flow and serves as an indicator of its adhesive, cohesive, or frictional properties. This resistance arises due to internal molecular friction within the fluid, resulting in a frictional drag effect. There are two key measures of fluid viscosity: dynamic and kinematic viscosity. Viscosity Types: 1. Dynamic Viscosity - Characteristic of fluids and plastic solids, dynamic viscosity quantifies a substance's resistance to deformation and is informally known as "thickness." 2. Dynamic Viscosity for Oil and Water - Conversion factors for viscosity, encompassing various oils, water, glycerin, and different temperatures. 3. Kinematic Viscosity - Includes units such as Stokes, centistokes, lentor, square meter/second, square foot/second, poise cubic centimeter/gram, and more.

Exif Eraser removes hidden data from photos before you share them. GPS coordinates, camera model, and capture time stay on this iPhone—nothing is uploaded, and there is no account. Photos can reveal more than the picture. A street, a home, the phone you used, and when you were there often live in EXIF, IPTC, and XMP tags. Exif Eraser shows those risks, then writes a cleaned copy. WHY IT MATTERS • Location: GPS can pinpoint the street or home where a photo was taken • Device: make, model, and lens can identify the camera you used • Timestamp: capture time can show when you were at a place HOW IT WORKS • Select one photo or a batch from your library (up to 30) • Review location, device, and timestamps at a glance—open any photo for full EXIF • Choose All metadata, or Location only if you want to keep camera settings • Save a copy to the Exif Eraser album, share a cleaned file, or replace the original in Photos PRIVACY FIRST • Processed entirely on your iPhone or iPad • No cloud, no analytics, no tracking, no sign-in • Save Copy keeps the original; Replace Original is optional and only runs when you choose it
