Nanoseconds to milliseconds java. concurrent. Supports Unix timestamps in seconds, milliseconds, microseconds and nanoseconds. Parameters: This method accepts a mandatory parameter duration which is the duration in milliSeconds. values. My code looks like the following now: Nov 26, 2025 · This blog will guide you through the process of accurately converting nanoseconds to milliseconds and remaining nanoseconds in Java, covering unit fundamentals, potential pitfalls, step-by-step implementation, and best practices. The goal is to combine the nanoseconds and milliseconds values to ensure the maximum resolution possible with the limit given. Jun 28, 2024 · To convert nanoseconds to milliseconds and handle cases where the nanoseconds value is less than 999999 in Java, you can simply take the division remainder by 1,000,000 (divmod) to obtain the milliseconds component. Using TimeUnit, how can I convert 665477 nanosecond to 0. This method may be used to iterate over the constants as follows valueOf. MIN_VALUE if conversion would negatively overflow, or Long. Nanoseconds are a much smaller unit of time compared to milliseconds, where 1 millisecond is equal to 1,000,000 nanoseconds. toNanos. It provides a set of predefined constants, each corresponding to a specific unit of time, including: DAYS HOURS MINUTES SECONDS MILLISECONDS MICROSECONDS NANOSECONDS In Java programming, dealing with time measurements is a common task. public static TimeUnit valueOf(String name) Returns the enum constant of this type with the specified name. Learn how to accurately convert nanoseconds to milliseconds in Java, handling values less than 999999 with practical examples. convert(665477L, TimeUnit. Actually, the precision of the value returned by nanoTime is always the same -- billionths of seconds. One millisecond is equal to one million nanoseconds (1 ms = 1,000,000 ns). 2. convert. Nanoseconds offer a very high level of precision, where one nanosecond is one-billionth of a second (10⁻⁹ seconds). Return Value: This method returns the converted duration as NanoSeconds. Below program illustrate the implementation of TimeUnit toNanos () method: Program 1: import java. Oct 16, 2025 · In this blog post, we will explore how to perform this conversion in Java, including core concepts, typical usage scenarios, common pitfalls, and best practices. , not all systems have a clock that counts individual nanoseconds, and so the clock might only tick on 100 or 1000 nanoseconds and you will only ever get multiples of that. On the other hand, milliseconds are less precise, with one millisecond being one-thousandth of a second (10⁻³ seconds In Java programming, dealing with time measurements is a common task. NANOSECONDS); This always gives 0 but I need decimal points In Java, converting nanoseconds to milliseconds can be easily achieved by understanding the relationship between the two units of time. Parameters: duration - the duration. e. The string must match exactly an identifier used to declare an enum constant in this type. The goal is to combine the nanoseconds and milliseconds values to ensure the maximum resolution possible with the limit given. Understanding TimeUnit TimeUnit is an enum, included in the java. 000. *; import java. Date; class GFG {. Two frequently used units for measuring time are nanoseconds and milliseconds. Conversions from finer to coarser granularities truncate, so lose precision. For example, to convert to milliseconds we must divide the result in nanoseconds by 1. Learn to create DateTimeFormatter in Java 8 for handling milliseconds, microseconds, and nanoseconds with clear examples. Another pitfall with nanoTime () is that even though it provides nanosecond precision, it doesn’t guarantee nanosecond resolution (i. Time can be represented in various units such as nanoseconds (nano) and milliseconds (milli). 665477 millisecond? long t = TimeUnit. Convert milliseconds to date-time. how often the value is updated). Returns: the converted duration, or Long. concurrent package, that represents various units of time, ranging from nanoseconds to days. public long toNanos(long duration) Equivalent to NANOSECONDS. util. MILLISECONDS. Link to a moment. This is for comparability with the sleep / wait methods and some other external library that gives out large nanosecond values. MAX_VALUE if it would positively overflow. public long convert(long sourceDuration, TimeUnit sourceUnit) Converts the given time duration in the given unit to this unit. In Java programming, dealing with time measurements is a common task. The accuracy can vary, i. java time milliseconds nanotime I'm wondering what the most accurate way of converting a big nanoseconds value is to milliseconds and nanoseconds, with an upper limit on the nanoseconds of 999999. convert(duration, this). Sep 20, 2025 · The goal is to combine the nanoseconds and milliseconds values to ensure the maximum resolution possible with the limit given. public static TimeUnit[] values() Returns an array containing the constants of this enum type, in the order they are declared. 3svxr, mv1qp, 8dqr, ldgr, yoayi, gdjrd, 4vlzi1, jov2im, iupvq, mz3k,
