  • Numbers to Words Converter
    Convert numbers to words in English. Spell any number, format as currency (dollars, euros, pounds and more), or write check amounts, with selectable letter case.
  • Digits to Words Converter
    Convert digits to spoken words character by character (123 to "one two three"). Read tracking numbers, dates, SSNs and serials in 12 languages with case options.
  • Computer (Digital) Storage Units Converter
    Convert digital storage between bits and bytes, decimal (kB, MB, GB) and binary (KiB, MiB, GiB) units. Free, accurate converter with the IEC standard explained.
  • Screen Ratio Calculator
    Calculate a screen's width and height in inches from its diagonal size and aspect ratio (16:9, 4:3, 21:9). Free instant screen dimension calculator.
  • Parity Bit Calculator
    Calculate the even and odd parity bit for any binary data. Counts the 1 bits and shows the parity bit needed for error detection.
  • Pixel Aspect Ratio Calculator
    Calculate Pixel Aspect Ratio (PAR) from stored pixel dimensions and display aspect ratio. PAR = DAR ÷ SAR, where SAR = stored width ÷ height.
  • 4:3 Aspect Ratio Calculator
    Calculate 4:3 aspect ratio dimensions instantly. Enter a width to get height, or a height to get width, using the classic 4:3 standard ratio.
  • Odd Parity Bit Calculator
    Calculate the odd parity bit for any binary string. Determines the parity bit so the total number of 1s (data + parity) is odd, for error detection.
  • Portrait Aspect Ratio Calculator
    Calculate the portrait (vertical) height from a given width and aspect ratio. Free tool for photos, video, social media and print layouts.
  • Even Parity Bit Calculator
    Calculate the even parity bit for any binary string. Counts the 1s and returns the parity bit that makes the total number of 1s even.
  • CSS Aspect Ratio Calculator
    Calculate the simplified aspect ratio from any width and height, plus the padding-top percentage for responsive CSS aspect-ratio boxes.
  • 16:10 Aspect Ratio Calculator
    Calculate the missing width or height for a 16:10 aspect ratio. Enter one dimension in pixels and get the matching size instantly.
  • Bandwidth Delay Product Calculator
    Calculate the bandwidth-delay product (BDP) from link bandwidth and round-trip time. Find the ideal TCP window size in bits, bytes and KB.
  • Uptime / Downtime Calculator
    Calculate allowed downtime for any SLA uptime percentage (99.9%, 99.99%, etc.) per day, week, month, or year — in days, hours, minutes & seconds.
  • Baud Rate Calculator
    Calculate baud rate (symbol rate) from bit rate and the number of signal levels (M) for M-ary modulation. Free online baud rate calculator.
  • RAID Capacity Calculator
    Calculate usable RAID storage capacity for RAID 0, 1, 5, 6 and 10. Enter disk count and size to see usable space, overhead and efficiency.
  • Streaming Bitrate Calculator
    Calculate video/audio file size and required bandwidth from bitrate and duration. Convert Mbps and seconds into MB and GB instantly.
  • RAM Latency Calculator
    Calculate true RAM latency in nanoseconds from CAS latency (CL) and memory speed (MT/s). Compare DDR4 and DDR5 modules instantly with this free tool.
  • Audio File Size Calculator
    Calculate uncompressed audio file size from sample rate, bit depth, channels, and duration. Get size in bytes, KB, MB plus the bitrate for WAV/PCM.
  • Video Frame Size Calculator
    Calculate the average size of a single video frame in bytes from bitrate and frame rate, plus the total file size for any clip duration.
  • Image Aspect Ratio Calculator
    Find the aspect ratio of any image and calculate proportional resize dimensions. Enter width and height to get the simplified W:H ratio instantly.
  • TV Size Calculator
    Find the ideal TV screen size for your room. Enter your viewing distance and get the recommended 16:9 diagonal, width, and height instantly.
  • Pixels to Print Size Calculator
    Convert image pixel dimensions to print size in inches and centimeters at a chosen DPI/PPI. Find the largest quality print your photo can make.
  • TV Mounting Height Calculator
    Find the perfect TV wall mount height. Enter your seated eye level, screen height and tilt to get the exact bottom-edge mounting height in inches.
