Scala Architectural Scale vs VCF Pro

Let Scala Architectural and Engineering Scale change the way you measure printed drawings on the go and at your desk. With fixed and variable scales there is no limit to measuring a printed drawing of any scale, even if the scale is unknown. FIXED SCALES If you know the scale of a drawing, place your device on the drawing, scroll to the scale of the printed drawing and watch the chosen scale slide in. VARIABLE SCALES If the scale of a drawing is unknown, slide your finger on the variable scale and match the scale of one known element, lock it and use it to measure all elements on that drawing. MEASURING Slide the measurement slider in fixed or variable scale modes, along the scale to see the desired measurement displayed. SECONDARY UNITS Choose secondary units to be displayed while measuring, to quickly convert between metric, decimal feet and feet and inches. PRECISION Control the precision of the measurement units. —-— Scala Free Version includes: ARCHITECTURAL Fixed Scales: Full Scale (12”=1’-0”), 6”=1’-0”, 3”=1’-0”, 1 1/2”=1’-0”, 1”=1’-0”, 3/4”=1’-0” Variable Scale Range: Between full scale and 1/32”=1’-0” ENGINEERING Fixed Scales: 1”=10’, 1”=20’, 1”=30’, 1”=40’, 1”=50’ and 1”=60’ Variable Scale Range: Between 1”=10’ and 1”=300’ METRIC Fixed Scales: 1:1, 1:2, 1:5, 1:10, 1:20, 1:25 Variable Scale Range: Between 1:1 and 1:1000 Scala Full Version includes all scales above plus the following: ARCHITECTURAL Fixed Scales: 1/2”=1’-0”, 3/8”=1’-0”, 1/4”=1’-0”, 3/16”=1’-0”, 1/8”=1’-0”, 3/32”=1’-0”, 1/16”=1’-0”, 1/32"=1'-0" ENGINEERING Fixed Scales: 1"=80', 1"=100', 1"=200', 1"=300' METRIC Fixed Scales: 1:30, 1:40, 1:50, 1:75, 1:100, 1:125, 1:200, 1:250, 1:300, 1:400, 1:500, 1:1000 —-—

VCFPro is a petroleum cargo calculator for tanker crews, cargo surveyors, and shipper representatives — at sea or on shore. It replaces paper correction tables with instant, precise calculations, in an interface modeled on the handheld calculators the industry already knows. Enter a reading by °API gravity, relative density, or density, and instantly get: • VCF (volume correction factor) • Full volume-weight results — barrels, cubic meters, metric tons and long tons, in air and in vacuum • Crude, Product, and Lube table families • °F / °C switching for any region • Results matched to industry-standard petroleum measurement tables, to the decimal No more flipping through table books. Enter your reading, get your numbers — fast, precise, and ready wherever the job takes you.
