1,000,000,000 in the context of "Apoptosis"

1,000,000,000,000 (one trillion on the short scale; one billion on the long scale; one thousand billion; one million million) is the natural number following 999,999,999,999 and preceding 1,000,000,000,001. It is known as 10 kharab, 1000 arab, or 1 lakh crore in the Indian numbering system.

Billion is a word for a large number, and it has two distinct definitions:

• 1,000,000,000, i.e. one thousand million, or 10 (ten to the ninth power), as defined on the short scale. This is now the most common sense of the word in all varieties of English; it has long been established in American English and has since become common in Britain and other English-speaking countries as well.
• 1,000,000,000,000, i.e. one million million, or 10 (ten to the twelfth power), as defined on the long scale. This number is the historical sense of the word and remains the established sense of the word in other European languages. Though displaced by the short scale definition relatively early in US English, it remained the most common sense of the word in Britain until the 1950s and still remains in occasional use there.

American English adopted the short scale definition from the French (it enjoyed usage in France at the time, alongside the long-scale definition). The United Kingdom used the long scale billion until 1974, when the government officially switched to the short scale, but since the 1950s the short scale had already been increasingly used in technical writing and journalism. Moreover, in 1941, Winston Churchill remarked: "For all practical financial purposes a billion represents one thousand millions..."

India is a union consisting of 28 states and 8 union territories. As of 2024, with an estimated population of 1.484 billion, India is the world's most populous country. India occupies 2.4% of the world's area and is home to 17.5% of the world's population. The Indo-Gangetic Plain has one of the world's biggest stretches of fertile not-deep alluvium and are among the most densely populated areas of the world. The eastern and western coastal regions of Deccan Plateau are also densely populated regions of India. The Thar Desert in western Rajasthan is one of the most densely populated deserts in the world. The northern and north-eastern states along the Himalayas contain cold arid deserts with fertile valleys. These states have relatively low population density due to indomitable physical barriers.

Giga- (/ˈɡɪɡə/ or /ˈdʒɪɡə/) is a unit prefix in the metric system denoting a factor of a short-scale billion or long-scale milliard (10 or 1,000,000,000). It has the symbol G.

Giga- is derived from the Greek word γίγας (gígas), meaning "giant". The Oxford English Dictionary reports the earliest written use of giga in this sense to be in the Reports of the IUPAC 14th Conférence Internationale de Chimie in 1947: "The following prefixes to abbreviations for the names of units should be used: G giga 10×." However, it was already used in 1932 by the German organization Verband deutscher Elektrotechniker.

English trust law concerns the protection of assets, usually when they are held by one party for another's benefit. Trusts were a creation of the English law of property and obligations, and share a subsequent history with countries across the Commonwealth and the United States. Trusts developed when claimants in property disputes were dissatisfied with the common law courts and petitioned the King for a just and equitable result. On the King's behalf, the Lord Chancellor developed a parallel justice system in the Court of Chancery, commonly referred as equity. Historically, trusts have mostly been used where people have left money in a will, or created family settlements, charities, or some types of business venture. After the Judicature Act 1873, England's courts of equity and common law were merged, and equitable principles took precedence. Today, trusts play an important role in financial investment, especially in unit trusts and in pension trusts (where trustees and fund managers invest assets for people who wish to save for retirement). Although people are generally free to set the terms of trusts in any way they like, there is a growing body of legislation to protect beneficiaries or regulate the trust relationship, including the Trustee Act 1925, Trustee Investments Act 1961, Recognition of Trusts Act 1987, Financial Services and Markets Act 2000, Trustee Act 2000, Pensions Act 1995, Pensions Act 2004 and Charities Act 2011.

Trusts are usually created by a settlor, who gives assets to one or more trustees who undertake to use the assets for the benefit of beneficiaries. As in contract law no formality is required to make a trust, except where statute demands it (such as when there are transfers of land or shares, or by means of wills). To protect the settlor, English law demands a reasonable degree of certainty that a trust was intended. To be able to enforce the trust's terms, the courts also require reasonable certainty about which assets were entrusted, and which people were meant to be the trust's beneficiaries.

A billionaire is a person whose net worth is at least one billion units of a given currency, typically USD. It is a sub-category of the concept of the ultra high-net-worth individual. The American business magazine Forbes produces a global list of known U.S. dollar billionaires every year and updates an internet version of this list in real time. The American oil magnate John D. Rockefeller became the world's first confirmed billionaire in 1916.

Nineteen individuals had attained the status of centibillionaires, each with a net worth of at least $100 billion, as of October 2025. As of March 2025, there are 3028 billionaires worldwide, with a combined wealth of over $16.1 trillion, up nearly $2 trillion over 2024.
